Sorry, we meant #painworthy 😢

Their chemistry is so so so unbelievably natural….. No need extreme kissing scenes - their dialogues, the way they look at each other , their eyes “tell” so much …. feel so pure and so sweet ….. Haha I wish they can be a real-life couple 😅😅😅😅

Kim Tae Ri and Nam Joo Hyuk is one of the best pairings in K-drama history. I will never forget and never regret the eight-week I'd spent to watch it. It perfectly portrayed "youth": dream, spirit, rebel, justice, hard work, failure, friendship.. and first love. Twenty five, twenty one is one of my favorite K-drama all time ❤

Despite the sad and unsatisfactory ending, Kim Taeri and Nam Joo Hyuk were really brilliant in this drama. Made us happy for weeks before making us heartbroken.

Twenty Five Twenty One taught us that the most difficult aspect of loving is not receiving the love you want, but the longing you feel when the person you want to offer your love to no longer feels the need to receive it.

They have so easily taken the title of "Favourite kdrama couple" for me.. They are so good by themselves, but magical together. Hoping for more dramas and movies with them as the leads.

Tae ri is deservedly getting a lot of praise for her role, but I just wanna say nam joo hyuk really stepped up his acting game too. He totally elevated the role of yi Jin, I can’t wait to see what kind of acting roles he takes on in the future.

Binge-watched for 4 days. When this became so popular last year 2023 and knew what the ending, i was thinking maybe i'll skip. But im glad i decided to watch it. It feels like a reply 1988 kdrama, very light but engaging. The story of how Hee do and yu rim friendship started, i cried in all their touching scenes. When yi jin first said I love you in the bridge scene made me feel like a teenager again. It is a masterpiece. Just like my favorite reply 1988.

baek yijin and na hee do’s love story is the purest form of love i’ve ever seen in kdrama. thank you so much to 2521 team for giving us this masterpiece. baekdo will forever have a special place in my heart

Every scene holds such deep and beautiful meanings 0:21 *I don't need a rainbow* such a simple yet beautiful. Its the type of love where you're inlove with the PERSON and not the romantic attraction. That's what makes their love so special. It started off as a friendship, which turned into platonic love, which slowly blossomed into deep love romantically. 0:32 The song playing in the background, and the lyrics *i thought it'd last forever, our 25 and 21* They already foreshadowed the ending in ep 2. Which makes it all even harder to watch all their swoonworthy moments. I still believe they ended up together in my imagination

Every lines, every touch, every moment with them together worth more than thousand kisses. Thank you for teaching us what the purest love is, Na Hee Do-Baek Yi Jin..

"Some people are meant to fall in love with each other but not meant to be together. " Sadly, not every love gets to have a happy ending. Sometimes, two people don't need to end up together to thrive. First love's something that you can look back on, learn something from it, grow because of it and forever cherish it. At least their love got a bit of a closure at the end even if it did not have a satisfying conclusion. Not many people in real life got to do this with their first love.

they’re one of the best pairings ever yet we barely got any interviews with both of them :(

I still haven't gotten over any of these moments 😢 It might be physically impossible for me to get through this video 😭

To me, one of the best K-Dramas I have ever watched! Kim Tae-Ri acting made this series a true masterpiece. 💖

The chemistry is top notch. They don't need to have steamy scenes...the intimacy came from the way they looked at each other and the powerful lines....This is a love story, simple and pure

Why do you do this to us swoon???💔🤍 I love them, i love their love… even in heart break their love was beautiful.🤍🌈

The best chemistry I've ever seen in any k-drama. They're more than that. Every moment was so precious. I will never get over this one!!

Kudos to Nam Joo Hyuk and Kim Taeri for pulling off their characters very well, their acting is superb and I miss this couple so much huhuhuhu. Baekdo and Namkim for the win. I love you guys so much.

Just when I'm about to move on and accept the ending, here comes all the BaekDo moments showing and proving why they should end up together. We are never going to move on from this, are we? 😢

they supported each other, they rely to each other, they love each other, they grow together, they become happy together but they also hurt each other. maybe their love story is only a chapter and a beginning of their lives. that brief moment, first love and their youth are all beautiful memories that once made them happy

That’s why Kim Taeri is one of the best actress and Nam Joohyuk always Good 👍🏼 they both shine on this drama, giving life and meaning to the drama..

Never a fan of Nam Joo Hyuk acting before.. Idk why his pairing with FL always get overshadowed by SML except for weightliftting fairy drama. In here, he really embodies his character as BYJ and I don't think other actor can top this version of BYJ. His subtle facial expression and emotion really tugs the viewer feeling. As for Kim Tae Ri, i avoid her until 25 21 drama. I wonder why people always hype her in korea. Now i get my answer, she has her own unique charm when acting. Her clear crystal eyes really stand out when she acts. Their unexpected chemistry is definitely a surprise to me. They succeed in proving my first impression was totally wrong. They are a total opposite but definitely fit like gloves. This drama is the definition of nostalgia hitting you so hard that it creates a bittersweet feeling of revisiting those past moments again.

BAEKDO WILL NEVER BE FORGOTTEN THEIR LOVE JUST SO BEAUTIFUL

pls let Kim Taeri and Nam Joo Hyuk reunite again in another project. Their chemistry is too amazing to only be seen in one drama 🤍🙏🏼 Manifesting!!

Butterflies and heartaches are what I feel with this video. Mixed emotions huhuhuhu

Kim Tae Ri and Nam Joo Hyuk have an incredible chemistry that hooks millions of people to support them.. Netflix I wish they will have new projects together. Drama or Movie we will support them with all of our hearts. 💕

I am crying againnn!!😭😭 When will I heal from this drama?!?!💔 Their love is just soo pure and heartwarming

I never imagine the way how this drama ended. Their foundation of love is so strong, that kind of love was definitely worth fighting for. Also their characters weren't that kind of persons who will give up easily. Kinda bit disappointed how the writer ended their story. But overall twenty five twenty one is truly a masterpiece!

The eyes, the scenario, the feelings, it is like its embedded in the history and meant to happen no matter what. It is indeed destiny for yijin and heedo. I wanted to thank the cast and the staff for making this wonderful drama that comforted me for 2 months. I will surely continue to root for Kim Taeri and Nam Joohyuk! (wishing baeksang for KTR and 2521, fighting!) ps. I experienced the 5 stages of grief after the ending. And I finally can say that no matter what the ending I just wanted to root for their happiness.

One has to be really very strong to rewatch this series ,it's really a roller coaster of emotions and the playlist is awesome

i can’t imagine anyone else playing these characters, i’m convinced if they were played by someone else it wouldnt even be half as good. it’s really magical when all the right people come together to tell a story.

Every moment every line broke my heart after watching the episode 16 it's not fair. Their acting was so realistic that you can barely tell that they are acting. Thinking about their break up I just couldn't hold my tears

this drama is written beautifully, although the ending isn't “perfect”, but that's the reality, this drama will definitely be one of my favourite for a long time. although the chances are small, i still hope there will be a special episode or season2, thank you to the twenty five twenty one team for this amazing drama !

This movie broke me who ever is the writer deserves their pay and much more it was incredible and heart warming

I tried watching another kdrama after finishing this, but I only made it to episode one 'cause I keep on coming back to this drama, Baek Yijin and Na Heedo made it too hard for me to like another couple. I am emotionally invested in them. 😭💔

The way they express their feelings mesmerized me every time... Their chemistry never get old...

This drama is LITERALLY UNDEFEATABLE AAAAA

miss them so much 😭🤍 they have the purest true first love

My Alternative Ending: Years go by. Its now 2022. Heedo still holds onto the past regrets of their breakup. She often wonders what their life would be if they gave it one more try. She goes to the tunnel. One last time, to reminisce about that youthful summer, that blossoming love. Minchae goes back to her ballet classes and decides to pursue her dreams. Just as Heedo gets out of her car, she sees a man, who looks like he's in his late 40s. He's staring at the tunnel when suddenly their eyes meet. She lets out a small gasp. Those eyes. How are they still the same even after so many years? He takes a step forward. 'Well well, if it isn't the legendary Na Hee-do' he smiles. The minute she hears the tone of his voice, she knows its him. Baek Yijin. 'Baek Yijin.' she says. A name she hasn't said outloud in years. 'Have you been well, Heedo?' 'Yes. I'd like to say that. What about you?' He hesitates for a moment, 'If I'm being completely honest, I haven't been that well'. Heedo can feel the tears forming in her eyes. 'Me neither.' she says, almost in a whisper. He takes a few more steps forward, and looks at her. In a way of asking if he can come closer. She nods. Now they're only 4 feet apart. 'I've missed you.' -The End

Definitely one the best series I have watched can't bear the pain at the end but other than that this series is a masterpiece will always cherish this one . Kim Taeri and Nam JooHyuk deserve all our love and appreciation they just lived as the characters. Hope we get to see them together in future projects

I only recently realized we have only one real kiss throughout the show , except for that mew hear kiss from Heedo, this just shows that their chemistry is so good and that skinship is not all. We could have gotten another kiss if not for the ending, i badly need a happy ending drama with these two as leads again

The shoelace scene still physically hurts my heart

Can I just say that this was and always will be a legendary drama because of the writing, the subtleness, the cast , the dialogues.... Everything... ❣️❣️🥺 "You drive me crazy"

I decided to watch ep 16 again for the second time today, and I thought I'm gonna cry again and be heartbroken. But strangely enough, after more than a week of recovery from the heartbreak, it gave me a feeling of closure. I guess it has now transitioned to a bittersweet nostalgic memory of mine. Thank you for this drama. Not only did Baek Yi Jin and Na Hee Do bring out the best in each other, but it also brought out the best in Nam Joo Hyuk and Kim Taeri as well. I'll probably watch this drama again after many months, but for now I'm gonna look forward to their next projects. I'll be cheering for you!

their breakup scene at bus station is the most painful one 😭😭 still not yet recovered from that scene 🤧😭

Never have I ever kept coming back for a drama. Kim tae ri's acting was so surreal. Glad that she bagged best actress baeksang nomination. Hope she wins too. 🥺

Kim Tae Ri nailed this role of an 18 year fencing sportswoman to the hilt. It is a feat for this 32 year old actor to play the role of an 18 year old and get away with flying colors.I thought she was just in her 20s. It is a casting coup with this leading actor. Too bad I was hoping they would have kept it to the end, as KTR 's daughter was going through her diary.Ah, but sometimes, life ends that way.

Kim Tae-Ri is soooo perfect for this role. Definitely one of the most beautiful love stories I have ever seen.

The best chemistry i 've ever seen in kdrama🥰

Still broke my heart how their love story ended but they molded each other perfectly where it leads them achieved their dreams..we broke down because we really love them both and they brought us reality which hits us...they love purely but they are not destined each other..❤❤😊

I am crying again, this drama and the chemistry between Kim Taeri and Nam Joo Hyuk is so real, they made me feel all emotions!

Yijin and Hee Do not getting back together is not a bad ending but an expected one. It has been brilliantly built up and foreshadowed since ep 3. Yijin knew even before they got together what kind of ending they will have if they crossed that line which eventually happened. It's the reason why he tried to put distance between them bec he doesn't want to subject Hee Do in a relationship with disappointments bec he knew deep inside he couldn't promise to always be there for her. Hee Do took risks, but throughout their relationship, she finally accepted the reality of it while it was happening and saw that the present selves have no future together. Both of their characters stayed consistent at their cores from the start and end of the drama. They grew up at some point, but also grew apart from each other. Hee Do has always been a straightforward character. She started recklessly pursuing what she wants but grew to handle people and circumstances better. She always stayed true to her principles and what she believes is right even if it was breaking up with the person she loved bec it was no longer serving them both. Yijin has always been someone who has a massive sense of responsibility and has a tendency to internalize emotions he shouldn't be responsible for (paying his father's creditors, shielding his bro from the harsh reality in life, feeling sorry for the deaths bec of the negligence of a construction company, and lastly, the 9/11 attack.) Yijin's traumatic experience with 9/11 fully cements a world without Hee Do, beyond personal troubles and relationships, and opens the harsh realities of life and the meaning of what true public service is. It is a world that Hee Do won't truly be able to relate and empathize with (thus why her support isn't reaching Yijin anymore and why it's no longer working for him.) Their time together was both beautiful and bittersweet. They both knew that it wouldn't last forever. That's why they both took risks in getting together as long as they can. Yijin knew he was hurting Hee Do by missing out a lot but he trusted her faith in him. But there's only so much patience and sacrifice a person could endure before they ran out of emotion to give. She grew tired and got emotionally exhausted. Tbh, she was the one carrying their relationship together. A courageous leap of faith considering the experience she had with her mother. Hee Do's empathy, unwavering support, and understanding were what drove Yijin to get back on his feet again during his lowest point in life. Yijin's presence, support, and guidance were what comforted Hee Do in an important phase in her life. But now, the 25-year-old Yijin and 21-year-old Hee Do are both adults who want different things in life. Yijin has a strong sense of public service and drives to excel in his career, while Hee Do lets him go bec she's no longer the support he needs at that stage in his life. It also boils down to Hee Do's self-worth, accepting that she deserves a man who can be present at her side. Both of them prioritize their goals and dreams, with Yijin moving to New York and Hee Do busy with her international competitions. Both also won't truly be happy if one of them sacrifices for the sake of their personal relationship. The best solution is to let go amicably on good terms but it wasn't a satisfactory breakup. Even in their last moments together, they weren't seeing eye to eye. That's the only regret Hee Do has in that phase in her life. It's a very realistic ending and a meaningful one.

despite how the ending turned out i want to experience this kind of love

I just love the way how Baek Yi Jin look at her everytime❤❤❤

No any other drama has hurt me this way, even after months of watching it whenever I come across any of the clips, it breaks my heart the same way it did before😭😭😭 The emotions that people want to experience and the emotions they don't want to go through, we have witnessed both through this drama. I know it's just a drama but still it's not "just a drama" but something much more than that😭😭😭 It's just too good and too real. My heart aches again🥲🥲

The best drama I have watched..It's been days n I am still not over..Even though the ending was sad..This drama is beautiful in every way...Nam Joo Hyuk and Kim Taeri has nailed the characters so well..Baekdo will forever my favourite couple 🌸🌸🌸🌸🌸

This drama made me feel so much in so many ways. It is definitely one of my top kdramas that I've seen

One of the best chemistry they really bring the characters it seems so real … loving every moment of them 💕💕💕

I love their LOVE for each other. I admire their admiration for each other.

I didnt understand the hype of 2521 until i watched it. I thought i will regret watching it because of the infamous sad ending. But i m glad i watched it because what a journey it was. To witness their selfless love, support, growth, happiness. Each scene was heartfelt and so well visualised. KTR and NJH brought life to the characters and I believe nobody could have dont justice to their roles better than them. Yes i cried hard and the ending deeply broke my heart but i was wrong that i would regret it, i dont regret watching this materpiece. It now holds a very special place in my heart. 😔❤️

This drama remains in our heart, The best 2022 K-drama for me so far, the story written well, and the ending is so realistic, that's why we can't move on. Big clap to the cast specially to Joohyuk and Taeri! Congratulations to the successful drama! I will miss this cast and this beautiful series!🤍

I'm in the 15th episode now, they won't be together as everyone wants, but it's still a good series. A meaningful and promising series.

Why wasn’t Nam Joo hyuk not nominated for an award, he certainly deserves one for this drama. Love love him ❤️❤️❤️❤️❤️

This drama is unbelievable!!!! We can't even express with our full words or paragraph ❤❤❤❤❤❤❤❤❤❤❤❤so many emotions

Bawled my eyes out when Na Heedo started crying at 12:31. It was heart wrenching. 😭

I'm crying again because of this drama, the past is over, but memories have a right to be stored in my heart. oh first love

This short video makes me cry so hard. This drama will always be a precious and special memories of my life.

Even The Swoon cannot move on with them. #BaekDo and #TwentyFiveTwentyOne superiority indeed. Thank you for continuously feeding us contents like this. :)

Swoon, please invite both Kim Taeri and Nam Joohyuk again for games or commentary session. I watched 2521 because Taeri is in. I never fell for Joohyuk before..but now I want them to be lovers in reallife. I never shipped kdrama pairs this much before. 😭

I came here to watched the clip again because i miss this couple so much 😭💔 their chemistry is one of the best so far

What made this chemistry so pure and real is that it didn't rely on the looks or other physical appearance. It came out naturally because of the love yijin has for heedo and the other way around. What they had was pure love and just that, no other factors or elements. Love that came so unexpectedly and that was so giving and rare. That's why it hurt so bad when they broke up. They're love is one of a kind, very rare and very ideal. We were so entangled with the thought that they and what they had were perfect. As much as love can't make them last together, it was what made them grow individually as persons. At some point of their lives, they really deserved and completed each other.

Thankyou swoon .. I was waiting for this for a long time ....... I know this drama broke my heart but still it was the best and it will remain the best forever. Forever grateful to the writer and director and of course nam joo hyuk and Kim tae ri for giving all of us a drama that will be in our heart forever..... my weekends are not the same

Just like Baekdo, Namkim is also destined to meet each other. A great pair indeed.

they set kdrama standards so high we still cant stop talking about this show 🥺

Still one of the best pair of k-drama world. #BaekDoForever

Best show ever! Even though it broke my heart.. unbelievable acting and chemistry of the lead pair, shows what unconditional love truly means

I still haven't move on with the series and here I am watching this vid :(( Their eyes really tells how deeply in love they are with each other, thank you for showing what really is to be in love in a purest and amazing way, Na Hee Do and Baek Yi Jin. Your love for each other stays with my heart forever 😭 This is like the best series I've ever watcheddd!!! I'm still happy watching these happy and sad moments that you both experienced, despite the sad and realistic ending. Thank you 스물다섯, 스물하나! ♡

I will never be able to forget Hee do And Yijin.. And their rainbow love...

Despite I hate the end of this dram but I still and always love every scene of Na Hee Do and Baek Yi Jin, their interaction such a reflections ❤ ❤ ❤

This is what real love is. Thank you for such a beautiful story and such beautiful characters. 🥺💗

This one is my favorite drama for quite a long time. The main couple touched my heart so many times, and I still "tear up" every time I think of their break up scenes. Brilliant lead actors, I just adore them both. Nam Joo Hyuk has been a favorite since early in my KDrama-watching days, when I watched him in Cheese In The Trap. And the same for Kim Tae-ri in Mr. Sunshine.

Their chemistry is on next level. So natural and pure. Hope to see these two together again

This drama definitely become my all time favorite drama, i swear!!

I just can’t get over the ending 😭 How many of y’all rooting for season 2

This kdrama will always have a special place in my heart! 😭🥺❤

I can’t stop missing them in twenty-five and twenty-one drama. Please let them together again in any way, like talk show or Vlog.

i've cried a lot until now, i miss them sm how can i move on?I dreamed about them these days.Btw, this is the best kdrama i've seen in my whole life, always suport them in the future. Thank you 2521 team for doing this masterpiece.Love u NamKim, yall th best

Even with the ending this drama has automatically become my top 3 kdrama of all time...and njh and Kim Tae-ri have become my all time favorite.....I love them so much and I want them in another project 🥺🥺🥺

Every time I hear BIBI - Very, slowly - it just pulls at my heart strings and makes me think of all the #BaekDo moments.

I have never cared for a kdrama couple the way I care for them. These characters and their relationship mean so much to me. Even though I know they are not real, I still hope they lived happy lives. Thank you Kim Tae ri and Nam Joo hyuk for giving Hee do and Yi jin such beautiful hearts and souls.

Na Hee Do and Back Yi Jin will always have a special place in my heart🫰🏻

They have the sweetest and most emotional story.

Thank you producers for making me cry for two hours..

Best chemistry of kdrama history Vincenzo and hong cha yeong Hee doo and back ye jin Cheong san and on-jo Lim soo hoo and young ro

This drama taught me many things that I couldn't describe

one year but i can never get over this drama, the chemistry, the storyline everything just aligned perfectly

25-21 had a sad ending. But it stays in my heart until now🥺❤️

This show gave me something i didn't know i needed.. can't remember the last time when i was so much invested in a show or its characters.. this kdrama will be my favourite for a very long time, i am sure about it. ❤️❤️ (Those who have decided not to watch the show after knowing about the ending, my only request is just give it a try.) THIS SHOW IS DEFINITELY WORTH WATCHING NO MATTER WHAT. ❤️❤️ The acting, cinematography, character development, dialogues everything is just so damn beautiful ❤️❤️❤️❤️❤️❤️

Theyre one of the best couple in Kdrama. They have the chemistry. I love them both thatit really made me sooovery sad and even cried that they separated in the end. Its just so sad😩😩😩
