*Incorrect Start-Up dialogue* Suzy: What big hands you have! Nam Joo-hyuk: All the better to hold yours with, my dear.

Oh man.. Acting.. Nam Joo hyuk's acting is so on point that you can feel his heart fluttering.

Admit it everyone: THIS is even more heartwarming and fluttering than a typical kissing scene. I can't with the butterflies in my stomach 💕

Han Ji Pyeong is a typical KDrama lead. Successful, rich guy who loves you from a far. He's arrogant on the outside but is sweet deep inside. Never commits a mistake. Will support you secretly. He meets the girl and his personality softens. But Dosanie is a just a regular guy who is upfront with his feelings, awkward but dependable, shy but determined, flawed yet perfect. He is sweet towards his parents and his friends. His love is too pure for dalmi and he's willing to improve for her. He's the kind of person that will trust you and go thru the journey with you. This may be an unpopular opinion but in real life setting, NDS is the best romantic partner. We will never meet people as their perfect selves. the idea of discovering your strengths and weaknesses while achieving your dream together is beautiful. that makes dodal a great pair.

She should stop it, he almost got cardiac arrest🤣

I love how consistent dosan's personality is. He's funny because he's ridiculously logical and a tad awkward around people😂 It's a great balance with Dalmi's optimistic and idealistic personality.

I know this kind of troupe ain't new, but still I find it refreshing since it wasn't often used. Guy being embarrassed, shy, and giddy while the girl is more forward with her actions. It's a nice dynamic specially in the kdrama world filled with rich handsome jerks who always get paired with naive crybaby heroine.

Nam jo hyuk can make every single detail of the expression. The way he expresses his emotion is so natural that everyone can mistake it as real. He is growing in every single drama. If you see each and every drama simultaneously you will see the revolution of his acting. He is doing better and better each and every single act. You will get to see something new, something different in each project. I just love the way he is improving. I can just say he is revolving into a great actor. Fighting Nam jo hyuk. We, fans are rooting for you.😎😀😉😊

NJY’d acting is unreal. I could hear his heart beating. He’s so shy in this scene.

this drama doesn’t even need excessive skinship, just put these two in one frame is already heart fluttering for me 😂🤦🏻‍♀️

Idk if it’s just acting, but you can clearly see the tension in njh’s hands 😆😍

I was actually so happy she discovered his identity (fake persona) early on! It made less cliche and interesting!

I can watch this a million times. I won't get tired. They are so cute!

This scene is *AESTHETIC* A simple skinship yet brings out a lot of feels. Will totally give you butterflies 😍😍

do-san is underrated because they focus more on the second lead. i mean yes han jipyeong is a good boy and he might be the "first love" because of his letters. but as the episodes goes by,i think thag dal-mi is falling for the real do-san and i think that is beautiful. the feelings you develop irl is different from the love that you develop from letters.

He’s so cute and his expressions are everything

It’s been a long time since I’ve found a drama that I thoroughly enjoy. The story line isn’t boring, the pacing is good, romantic scenes aren’t cliché, and all the characters are likeable! It’s nice to finally see a male lead that isn’t stone cold and a jerk. I love how Dosan is a pure and innocent gentlemen. I can’t even bring myself to dislike the antagonist, which could be good? The drama is only in its beginning episodes so I hope they don’t screw up the storyline or characters.

I am dying for this couple, I never felt this type of butterflies on my stomach for a long time except from yizhan TT

I like Nam Joo-Hyuk's acting in this scene. He looks natural. Whenever an actor has to act like they don't care but they really do, I always watch them closely if their technique is cringy or not. I watch this drama bc of Suzy but I am surprised how good NJH is asan actor. His skills need more recognition.

this was the best holding hands scene ever!

Remember their almost first meet up? It was a love at first sight moment for Do-San. Even though he's shy, timid and awkward, he would do anything just to get close to her... just to win her heart. He may be pretending to be the guy in the letters but he was genuine the whole time. That's why I fell for him. Team Do-San since Day 1.

He looks like he’s gonna cry of happiness. They are both such good at acting

my heart blushed seeing the bis dalmi and dosan scene..

Nam Dosan might not be acting in this! Perhaps his heart fluttered automatically when he saw her🤣🤣 That’s why it looks so real

Thank you swoon for sporting Nam joo hyuk in this drama he deserve better sadly people are so bad for him while he is the main and his chemistry with suzy is way better than second lead hope you bring both NJH& suzy to play swoon games please

Dalmi just went from comparing hand sizes to hand holding omg❤️I love Suzy's character so much🥺🥺

This is my favorite scene till now in the drama and the way NJH performed is amazing! I can almost think of myself in his position and felt the same emotions 🙂😀

Whenever i watch this drama, i can feel the difference with another drama. Is it just me who think that start up has a different vibe? Even the sinematic sooo different. I love it Soo much

Refreshing to see that the first male lead seems to be the underdog in this drama (most kdramas have FML that are more successful and confident). Here, its finally right to feel like Im rooting for the better man instead of just the confident (first love) man that kdramas made me grew up in. If this is in another kdrama world, this is like you rooting for the ‘second lead’ vs the ‘first love main lead’ right? It feels that way for me. Sometimes i get insecure with what people are saying that Jipyeong should be the end game because he’s the first love, he’s more confident, successful, etc. But Ive been in that boat for most of the kdramas Ive watched. This time I want to root for the man who is always there for her (the guy who for most of the kdramas I watched would always be left behind). And this time, thankfully, I have high chance of not getting heartbroken. This is actually more like the reality of life. You dont always end up with your first love. You end up with the person who is always there for you and genuinely and loyally loves you.

Nam Do San: Fluttering way too much that he's not even looking at Suzy. Me: He's looking at me through the screen without looking at Suzy!!! (me fluttering)

I know this wasn’t sound like majority, but I love nam dosan so much, frankly speaking he’s innocent & kind I hope he quit play along with jipyeong and stood up on his own (he sure will be a decent businessman - can’t wait for the transformation) Also happy for chulsan finally he’s landed & living on (south) korean drama 😂

I'm smiling like an idiot while watching this 🙈😍

I like how Do San always first takes a few seconds and then follows his heart! Doesn’t hold back! Whether it was asking about the music box or getting into the bus! This scene could have been cheesy but Dalmi actually portrays innocence when holding his hand which makes it sweet. Also you can see that Do San is resisting every urge to fold his fingers over hers as it is not exactly the right thing to do since he doesn’t know if she was honestly just comparing the hand sizes! Lol! But when she makes it clear she wants to wrap her fingers over his, he explodes with the kind of joy that only tender new found love can bring. His face says it all as he reciprocates her actions! And they nailed it with the background music! This scene is truly iconic! Well done Start up!

Seriously why is everyone even guessing who will she end up with? No female leads choose the second lead. Dalmi will end up together with Dosan.

Love their chemistry........our cute Nam Joo Hyuk and Bae Suzy.

Best scene.. every boys wants to be nam joo hyuk at this scene.. 1:25

This scene is so perfect because all his adorably awkward expressions 🥰

Admit it, it's been over a year but this scene still gives you flutters. NJH's acting is very on point, that squinting of eyes, trembling hands, and uneasy sitting position, even deeply exhaling 💕👏🏽👏🏽👏🏽

The way their relationship grew over the episodes wow... so natural

Do San is too pure,, innocent and sweet... I love this couple❤️❤️

I can't with his expression 😂

The cutest first holding hand moment and they interlock their fingers at that...smile just automatically appear each time i watch this scene...suzy and nam joo hyuk are the cutest adorable beautiful pairing ever

it is just very simple yet so sweet and endearing! this drama is really gonna be the best drama in 2020!! just look at the OSTs lineup, we got Ailee, Red Velvet, Davichi, Gaho and many more 😭 i cant freaking wait for the new eps

Am I the only girl who wants a boy like Nam Dosan? I would die for it!!!!

"What big hands you have!" lol this reminded me a lot of Red Riding hood, the scene w/ the wolf 😂😂😂

This is too pure and cute and my heart is about to explode everytime I see this. Yes, I have this scene playing on repeat.

dosan u r very innocent n kind-hearted🥺 be happy with dalmi juseyooo🥺🥺 dalmi dosan🥺✊🏻

I got butterflies all over my body for this scene!!! Whaaah! 😍😍😍😂😂😂

The Swoon please we want Suzy and Nam Joo Hyuk exclusive content and Swoon Games. Do it for #TEAMDOSAN

This is one of the best scenes ever.Suzy’s acting is so good and I love her style and confidence in this scene.The way she grabs his hand is fluttering to say the least.Nam Joo Hyuk’s expressions are on point. Plus the song is cherry on top~

there was too many feels in this scene!!

y'all not going to believe how many times i watched this

Ehehehe I like how innocent yet fun Nam Do San is, I like how he sooo innocent that it's hard for him to handle the blood type thingy 😂😂 I'm fine if Dalmi ends up with either Dosan or Jiphyeong, but I still prefer Dosan :3 Both are charming, yes

Nam Joo-hyuk is such a Versatile actor.Been his fan since Who are You:School 2015...after that there's no end.❤He is BAE!!❤

This whole hand holding scene is not something new but somehow this scene brought smile on my face, it's so cute ♥ Suzy love you as Dalmi and Dosan too #StartUp

Suzy:Behave your hands!. And holds it. Nam joo hyuk:Oh men!Her hands are warm.Love it:) Smiling in the inside.:)

I'm so happy with episode 4 . Finally dalmi knows the truth. Rooting for main lead. Nam joohyuk ❤️

This is my favourite scene from start up 😍.... As soon as Dalmi holds hand, NJK heart beating like a drum....

Loved the way he was trying to hold her hand and got all nervous And when she hold his hand he was like okay🔥🔥 its done 😂😂

When I was watching the drama I felt like han ji pyeong was done wrong but now that I look back to it I feel like ji pyeong and Suzy wouldn't make my heart flutter like how do San and Suzy did 🤭

They are such a great actors. We can literally feel his heart fluttering. That's making me blush like I am in that scene😂😂❤️❤️

This was such a cute scene✨🙈 I couldn’t stop smiling😁😁😁😁😁😁

NJH he is awesome, I really can feel his excitement when Dalmi hold his hands, I really love this scene, I can watch this forever!!! I love them both their chemistry is unbelievably magnificent!!!

I love it that the caption of this vid uses the real names of Suzy and NJY instead of using their character names. I ship these 2 in real life 💓💓💓

The swoon giving us major swoon moment of Nam Joohyuk and Suzy Love this couple so much

Awww my ♥️...Nam joo hyuk confused and running towards the bus and suzy making a move and confirming her approval with a hand hold is making my heart so full of flutters...I'm gushing over their sweet bonding😍

Nam Joohyuk & Suzy looks so sweet 😍

so what if jipyeong is the first love? any first love can be destroyed by the true love which is dosan for me. in episode 4, we can see him and how eager he was to replace all what jipyeong did with dalmi, and it's now starting with his hand, a small thing but each step is a good one whether small or big.

0:40 best part it's when he look into Dal-mi's eyes. being so shy, he can't do it with people in general ♥

The hand comparison scene is just....too cute to handle. Nam joohyuk and suzy have so much chemistry. So far I'm in lovr with both leads, can't really choose between those two....

Lmao his face omggg... im in love with him!!! Also this drama makes so much butterflies in my stomach😂😂💞💞

BEST HOLDING HANDS SCENE SO FAR and very funny at the same time. Hahahaha I love the expression of NJH felt so real.🤣🐶🐰💜

Every time he flustered my heart had butterflies ❤️❤️❤️

Why is Dosan so cute bless his awkwardness haha

AAAAA OMG THIS IS MY FAVORITE SCENE!! 💕🥺

It’s gonna be almost a year since Start Up and I still love watching it and listening to the music✨✨✨

I usually don't watch ongoing dramas cause I can't wait till the next episode airs and gets translated to English... But for this drama I broke my rule and watched and I regret that decision😭😭 this drama is too good I am going crazy waiting for the next episode to air❤❤❤

His expressions make this scene the cutest :)

my favorite scene so far!

Really, in this exact scene I fell for Joo Hyuk's acting. I have seen a few of his acting but this one shows the spectrum of his acting skills the most for me 😂

Nam Joo Hyuk's acting😍🤭 His portrayal of the mixture of both awkwardness/shyness and happiness altogether is flawless. He is among those actors who can make you feel the emotions along with themselves.☺️😄❤️

Love han ji pyeong's character in this drama but I never questioned that Dosan will be the end game. Their chemistry is just soooo insane and their story together was so great and almost couldn't stand alone independently so I was team Dosan all the way.

I can really feel the "kilig" in here.. ohhhh my heart Nam Joo Hyuk 😙😙😙😍

I love this scene, can't move on

OMG!!!!! Can't ask for more... Cuteness overflowing.... Love Butterflies flying over everywhere...........

My fav bus scene😂

My fav scene so far..cant wait for the kissing scene..lol

So cute when he is so shy because holding hands 😊

Nam jo hyuk is prettier than most girls I know. 😍

Suzy's acting improved so much. I love her.

You go girl💃👍✊. I like that Dalmi takes initiative most of the time. And how shy Dosan is

Nam joo huk's reaction is all you need when your boyfriend hold your hands 😍😚, isn't it? That feeling is precious.

Nam Joo hyuk acting is great.. holds hands acting make me dugeun dugeun..💗💗 simkoong💘💘

Nam Joo Hyuk is such a talented person.Person with a good heart ❤

Their friends chemistry is awesome 😊😊😊 Bae suzy is terrific in her acting 😘😘😘👍

I couldnt stop smiling during this scene. This, ladies and gentlemen, is the birth of anothey simp for suzy lol i dont blame him

This is so KILIG!!!! Their chemistry is on full blast! Kyaaah! 💓💓💓

I am absolutely rooting for them hardcore. I know everyone wants jipyeong but... they match so perfectly. Aspiring dreams DONT work unless they have the mechanics. Plus she literally fell right into his lap in the most difficult time of his life and gave him more motivation than anything. Him doing the same for her and continuing to grow with and for her. Jipyeong deserves happiness too, not the way her and dosan do though 😭😭😭😭

Beautiful scene I love the innocence of Nam Do San

Words cannot describe how happy i was for Dosan!! Oh my god that first time you hold hands with your crush and he/she initiates it??? IT’S THE MOST FLUTTERING AND NERVE-RACKING FEELING! Then afterwards you won’t be able to move on easily and repeat that moment over and over in your head. More importantly, IT WAS HIS FIRST ROMANTIC EXPERIENCE! My heart was pounding as much as his probably
