This is basically Jaefans theme song as it should. Jaefans should protect Jaejoong at all cost.

Still one of my favourites even to this day. Can't believe it's already 10 years since the drama. It gives me nostalgia

You can’t be Jaejoong’s fans without knowing this song :D

There's something about the way he sings. The emotion is so sincere like he's singing it to someone he loves. It's the same with Ailee. Ailee sings a lot of her songs to the man who broke her heart and I honestly think JaeJoong is singing to the person he loves too. You can just tell from how sincere it sounds and the emotion in his voice.

It's been decided that this will be the song my fiancee and I will perform our first dance to at our wedding~

still in awe of this song in the year 2023

JAEJOONG is perfect! Like something about his voice is very appealing and it's very unique

Jaejoong AKA the Vampire in Protect the Boss. LOL my family totally thought he was a vampire kekekeke, but my goodness he is one fine human being with a beautiful voice! FIGHTING JAEJOONG OPPA ! Xoxo ^_^

he is a perfect person but i fear that he is very unhappy in love because all the best ones are, look at what happened to Marylin Monroe....I just hope he finds love whoever it may be

Sometimes I fangirl so much until I start crying...He's too perfect for a simple fan to handle, he's a whole package, from looks to voice and talent, he excels in everything!! Seriously is there something he cannot do!!??! He's iconic ! He's really the type of K-pop idol agencies are trying hard to make but they fail miserably! No one can ever be as perfect as he is! Not only he's a good vocalist, his voice itself is beautiful it's not only about training ! He was born with an angel's voice that is somewhere between women melody and male roughness and it sounds so so mesmerising !

It's very romantic that he always sings this at the end of his concerts!

Still hearing his song made realize how old im getting...

Oh lord, for me Jaejoong has the best voice the world

17/12/2020 -I am here again... Missed JaeJoong very much...

Sometimes I feel my peace is in his voice

Just started watching protect the boss and seriously, it's one of the funniest and nicest kdrama I've ever seen ^^ plus JJ's character is too cute haha

OMG Kim Jae Joong's voice is amazing!! Just perfect! :D

Jaejoong is my first bias in TVXQ, then i start to love Changmin, then Junsu, then Yoochun and Yunho. and all of them become my bias. i can't choose one. :D

This is what we called heaven voices :D He never fail to impress me with his talent and angelic voice Jaejoongie is always the best xD

I'm so happy that I consider myself part of that group of lucky ones who's heard this man sing. Jaejoong is amazing in so many ways unexplainable.

jaejoong just had a concert here in the Philippines. I got to see him for the 2nd time around and I miss him so bad. I will always love and support him no matter what.

Great voice, protect the boss is one of my favorite kdramas. It was soo funny.

i hate sad songs for it always made me cry... but this guy's songs is so awesome.... i'm so into them already.... if only i know hangul... then i would download .... all his songs... and carry it with me all the time... so whenever i feel down... i would listen to it... oh no, it wouldn't make me more depress... for it's like embracing a part of me that i always deny...

Jaejong's voice breaks my heart

Back at it again! April 4, 2023

Only some ppl can hook you just like dat he is one of them his voice full of emotions and charismatic, tell you the truth all were(db5k) their vocal are top best

jaejoong's voice really soft and sad... tears falling down my cheek T T

Amazing looks matched with a versatile voice that can melt. What is it about him that gets us falling for him...maybe cos we don't ever see him on the mainstream TV music programs ~ what is rare gets us hooked instead

listening to hero jaejoong sings this makes me feel like i'm in a sad-slow-motion-kdrama scenes.

Best voice ever

ジェジュンさんのやさしさが込められた曲ですね。いい曲だなぁ～!

WOYYYY INI OST KESUKAAN KU DARI DRAMANYA. YANG NGISI JAEJOONG NYA SENDIRI?????AHHHHHHHHH SUKA BANGET

I can't believe he sang this!! I had a feeling tho. ... beautiful ♥ lol

Undoubted, Jae Joong's voice is still the best, his control is really good.

I think about this song often it always brings me back to a very warm feeling I thought I forgot

i just finished the Protect the boss drama marathon ...worth watching guys

Watching this drama while on quarantine! Now at episode 5♡

Never got bored of this song

This song shows his rich voice in a way that differs from his days back in TVXQ, or any previous works with JYJ. It's really a matured mark of his singing career: the melody, lyrics, vocals and emotions are all spot on. It's more than just amazing...it's breathtaking.

This song is so sincere!!! I really like it :)

This is just burned into my brain in a very good way. It made me fall in love with scenes in the TV show and certainly added to the emotion. As a live performance song in concert with the audience singing along it moves me to tears. There have been many amazing ments 💚 with this song, it’s like an anthem for Jaejoong. It’s beautiful and holds up over time. I hope he always continues to perform it live. Thank you for posting with English lyrics and Romaji. Your effort are appreciated. Thank you for hard work! 🌺

This song gives me goosebumps. Especially when he is hitting those high note. I love his ANGELIC voice. Jaejoong oppa, saranghae!!!!

Jaejoong .. always makes me happy

Love this song~ Jae~ I love your voice~ so beautiful~

I like his voice...this song and all of his songs...!!!

This song makes me have a feeling that I want to cry.....actually it's really been a long time...I watch this drama when I was 9 years old...it's been a long time....I really like this drama,when I was small,I always go to bed a little late because of korean drama.The tv channel will air it like 8:30pm until 9:30pm at night....There was also other drama that I reealllly like such as: Rooftop prince Protect the boss School 2015 : Who are you Oh my ghost Princess Hours The moon that embraces the sun Let's fight ghost Dream High What happens to my family Shopping King Louie I am not a robot Strong woman Do Bong Soon

Since Kris left Exo this has been playing in my heart..

Am not a fan of kpop music but I start appreciating because of Jaejoong and this OST. He has a deep and soothing voice. I love it. More power! ❤❤❤

YOU ARE THE BEST OF THE BEST !

いつも優しさの歌声を届けてくれてありがとう。永遠のジェジュンさんは本当にすごく歌が上手だよ。たくさんの人のことを思いながら歌を届けておられるのもジェジュンさんの優しさがあるからなんだね。素晴らしい歌声を本当にありがとう。忘れられないよ。ずっとずっとずっとだよ。

I LOVED Protect the Bossfom beginning to end!!!

OMG listening to this song his voice sounds so amazing,powerful, smooth... i cant believe he said he used to be tone deaf 0_0 his voice is just wow ^_^

I love this song. This is my new addiction... I listened to this song on repeat for a couple of hours. It is absolutely perfect~!

I miss u

still my favourite song in 2023

maybe that's the reason why he sings so well, he once said in an interview that he puts all his emotion when he sings :)

I will forever be addicted to this guy. and to the song.

he's much more amazing when you hear his lifestory.

It’s been 11 years but this is still my most favorite kseries. I miss the old days 🥹 nostalgia ❤️❤️🥹🥹

i love this song

not just the lyrics or the melody is great but there's the way kim jaejoong sing it so great

2020 and still can’t move on

I miss him so much

I think I just broke the replay button.

JJ has got talents beyond measure!

jaejoong is so talented, just perfect. i didn' know a human could be so perfect, he i hot. i'm not korean, nor am i an American, hech, i'm not even white. And all i can say is, no race can compare with his angelic, face, voice. i love him so much. i just fall for him two days ago, and i all ready know everthing that is to know about him, LOVE YUNJAE, (I'M A HUGE SHIPPER, AND LIKE I SAID , I JUST LEARN ABOUT HIM TWO DAYS AGO) wish they were really a couple, and the group never disbannded.

Jaejoong has been more and more attractive, both his outlook and singing skills. DBSK has been a legend of kpop. JJ helps the legend continue and grow on its influence. Many people find out DB5K because of JYJ and DB2K.

OMG I love this guy !

I love this song,you can feel he puts all his emotion when he sing this song.Same as when the first time I heard S.K.K.S ost,invite me to find out who's singing that beautiful song.

One day i will meet him and thank him for all his greatness.

jaejoong dont worry baby im already in ur arms T-T such a sentitive sad song.

Jaejoong is perfect in every way, and words can't describe how beautiful his voice his. That high note...excuse me while I go faint.

the lyrics are so sad my god... JAEJOONG you are an amazing singer..you'l be happy becoz u deserve it.. just keep the faith, your love will stay yours forever, only yours :)

This song is just beyond what I expected. It's amazing. Jaejoong is just beyond what other idols are capable of :D

will always support him.. he has lovely voice and lovely face.. :)

God bless Kim Jaejoong
