One of the things I love about this duet is you know Jongdae's not holding back. He doesn't have to worry about overpowering powerhouse Liyin. Flawless performance. Seamless harmonization. These two should be each other's official duet partners.

I'm so impressed by Chen's mandarin :) His pronounciation improves after every performance! and I can't imagine how difficult it must be for him to memorize the lyrics.. kudos to him.

I love the way Zhang Yi Lcontrolled her voice to due softly with Chen, thats so professional :(( She made it even deeper and more tormenting. It is truly a duet ballad love song. Red Velvet Teacher yyyyaaannngggg

You know they're treasures when the lives sound just as good as the studio recordings.

Zhang Li Ying's voice control, technique, dynamism and vocal color are so good. She's really one of the best singers SM have. You can really hear in this song how she attacks the notes. Her voice is so powerful but she knows when to soften it to match the voice of her partner, damn, such amazing control. This basically proves how professional and how matured she is in singing. I can imagine her having duet to different type of voice because of her superb control. Really rare in SM. Too bad she's not promoted that much. Chen's voice is also awesome, definitely good for any type of songs but really shines more in ballads. :)

Really. Of the 3 language covers, this duo is the best. The best harmony and chemistry.

These two sounds best live, more in sync with each other and so passionate

I like when Zhang Li Yin speaks, her voice is soft then when she sings it's like woah o_o even Wang Lee Hom could not believe a voice came out of someone as young as herself back in the days & this has to be my fav. Version especially as these 2 look comfortable with each other; in an interview Chen mentioned her being a noona yet he wants to protect her like a younger sister & how they spent a lot of time together in order to perfect Chen's Chinese ^___^ ahhh so sweet this duet

장리인 목소리 진짜 좋아 뒷부분에 힘 실어서 부를때 진짜 소름❤

Chen's Chinese has improved a lot

중국어로 불러서 들을 때 뜻은 바로 알 수 없지만 뜻 해석 찾아보니까 가사가 정말 예쁘더라,,, 개인적으로 둘이 목소리 합이 너무 좋음

2023 yet still amazed by Jongdae’s voice! He and Li Yin voice blended perfectly!

To be honest, it's hard to judge one of these versions being better over the others... But, I guess that the Chinese version was more...emotional? Maybe because it's live, but I felt like Chen and Zhang Li Yin really connected and built a climax in the song and it was amazing x

There's no doubt vocal wise this duo outshines the other two versions. I strongly believe Chen is born to be a ballad singer and Zhang Li Yin is just amazing. she has so much control, her techniques are great and can effortlessly put so much emotions into the song.

zhangliyin's voice is so so so great!!!!!!!!

I've been following Liyin for years and despite a 5 year hiatus, she has never given up on her dreams and come back stronger and mature than ever. Such a nice performance from the two.

Zhang Liyin singing is beautiful~ Her smile at the end, she's so happy ^^

In my opinion i think this ver is the best than other ver because chen and his partner voice blend so well

YES ZHANG LIYIN IS BACK!!! Chen is an amazing and stable vocalist, but the Chinese version really shines because of her :) Ughh she deserves to get more of her own music out. Too much talent kept under a rock for too long....

I adore how Li Yin sounds even better live, it gives the song another vibe, you can feel the sadness. And Chen.....well, I love him no words needed

liyin's voice is so beautiful and chenn mann his voice kills me

I'm half Chinese, and seriously, I'm so proud of Chen 😊. His pronunciations were good. 👏🏻

첸~~~보고싶어ㅠㅠ

This version is far the best for me among the others. So happy to have discovered this talented singer as Zhang Li Yin, her voice is so powerful and it matches very well with Chen's. This song makes me have chills. Good job.

my favorite version!

I recognized Chen when I clicked the video but this Zhang Li Yin... I am so impressed by her singing! Amazing!

at first i didn't like this song, but now i'm in love with it, specially this ver

I love how they smile at each other at the end. And I thought: THIS is what a duet is about. Singing together, connecting through music. I've always been a fan of Zhang Li Yin and was super happy when I knew Chen has a duet with her. I love his voice and I love it more when it blend perfectly with hers. This is definitely my favorite version of of the three. Chenchenn you're getting better! Fighting :)

Their live is so beautiful

The chemistry is real. Wow....! Amazing.

Putting my Jongdae bias aside, I think this is the best version. They are both power vocalist and they blend so well together. It's always good to see Zhang Li Yin, she's so amazing

LI Yin is the epidomy of perfection when she sings. OMG she has a really soft and gentle touch when she sings and not to mention she can sing with power if the song requires it. Li Yin, really love this girl. I hope this means a comeback for her this year, i really hope so. THis girl is too talented not to be.

Zhang Li Yin is phenominal! Can't wait to hear more from her. And Chenchen

I fall in love with his voice and her voice. Even through i hate sm but i am a kind of person who admit if the artists have talented

Their voices... OMG... It's so soothing. Their voices compliment each other so well. They need a full album of endless duets together

Oh my God I can't lie this is the best duet here in the SM The Ballad. They comfortable with each other. It both pleasant to look and hear. Both of them nailed the song. No one voice over power each other. They sang with damn good comfortable chemistry. And they both got the feeling of this song. They understand how to express the song. Even I'm acknowledge a big fan of Taeyeon and Jonghyun but Chen and Ri In (Li Yin) did the best here. And also Changmin and Krystal ummm you know.

Yup, live performance is better than the recorded one. Thumbs up! Chen Chen Chen!

that girl brilliant voice i thnk she is the best vocalist in sm aside frm taeyeon and tiffany i like her voice so much :) i like chen also

Their voices are a match made in heaven. Finally, a woman with a voice full enough to compliment Chen's perfectly.

chen is so handsome when he is singing ! !

ZhangLiYin is great

Best version for me too. They both complement each other's voice perfectly ... sounded like an OST for a drama. SM really need to get Zhang Li Ying out more, her voice is so beautiful and full of emotion, her talent is seriously under utilized.

Chen sings so beautifully, I love it!!!!

Chennnn yaaaaaa i love uuu

Falling in love with this version , I love both Chen and Zhang Li Yin !! They are so GOOD !! 4 Thumbs up for their performance, Their voices match each other well ..

The best couple of SM Ballad..their chemistry really great.

Zhang Li Yin so good. Great voice!!

His pronounciation in this live is much better than the studio version!!

Zhang Li Yin's smile at the end so beautiful and I'm touched bcz of this :((

I'm really impressed by the female vocalist. Chen's veins are popping out while homegirl is just chillin' as she performs. So effortless.

SM should treat Zhang LiYin better, her voice is just amazing! LiYin fighting!

Glad her voice has improved dramatically over these past 8 years. It was really flat back then and when she hit those high notes, oh goodness... Huge improvement, she sounds beautiful!

This what you call a true duet performance..........You can really feel the emotion of the song and the emotion of the artist singing the song........

His eyes and the way he is so serious and sincere really melt my heart❤️❤️❤️❤️❤️❤️ looks best in black suit

tbh i like this version better! chen's and liyin's voice compliment each other really well!

Li Yin's voice is the best in SM for female singer... You will know is her when you listen her voice, doesn't like other when you hear their voice and you don't know who is it... Her singing skill improved so much... Don't keep her any more and give her a comeback, she have such talent...

Both are so talented

listening to this version again. I wish that SM would make more project for this duet. Liyin and Chen's voice are perfectly fit each other, the both of them have the same power in ballas songs. if SM would release and album of this duet, I will surely buy it without second thought. so please SM, don't waste their talent especially Liyin

her voice makes me melted with the song since the 1st i heard this song, this is the winner out of 3 version.. their voice gave different color to this song and the touch the soul of it, hands up both of u, love them even more

Chen & Zhang's voice click so well, amazing synchronisation.

Oh my goodness Zhang Li Yin freaking killed me with the emotions portrayed in her voice. This is why she's one of my favorite soloist please SM we need more of her promotions and honestly combine that with Chen's amazing vocals they make one heck of a duet. Freaking cried so much listening to this version and even though the MV already made me cry this just add so much more emotions.

Omg why haven't I seen this lady before?! She's so freaking good i hope SM has more for her in the future.

ZHANG LI YIN

Zhang Li Yin voice r so good, i still remember when she sing with TVXQ, its the best moment for me ever! chen singing is nice too, i like the way he sing chinese : )

Woah.. I fell in love with them.. Their strong and powerful performance have such great chemistry. Kudos and bravo to ChenChen and LiYin!!

This song made me fall in love with Chen even more than I already am. His voice is heaven and Liyin's voice sounds so beautiful accompanied by Chen's, jjang!

Zhang liyin it was amazing!! really i totally fall in love from this song for her voice! but obviously chen was amazing to! but i think Liyin deserves more attention, she's an amazing singer!

it's been forever since this came out.... but I still think this is the duet with the best voice-harmony that sm ever released! I need them to do more songs together!

chen developed his mandarin speaking skills bc he's been close with the chinese members even before debut. they grew on each other so much that jongdae even volunteered to be in exo-m

Best version ever😘

im speechless CHEN and LI YIN we're daebak.. they convey and express the feeling and emotions of the song perfectly.. AMAZING

I love this version the most... They melt my heart, especially, Chen...OMG

Zhang LiYin!! I feel like crying when she started singing. It's really been a while since I saw her on stage. And Chen is really good.

Chen was so talented from the beginning , we need another collab from them

Their voices took me on a rollercoaster ride... filled with emotions. At first, even though I didn't understand what they were singing about I felt their story!! Chen you blow us away everytime you sing & Zhang Liyin has a beautiful voice!! Both are talented singers!! Loved it!!

I love Chen,his voice is strong powerful and everything good but I was thinking how lucky he is that he gets to sing with Zang Li Ying,I mean anybody would be honored to sing with a voice like hers.That said the CHN version of Breath was my favorite,followed by Japanese version.

chen and liyin are daebak!!!!

Zhang Yi Lin is no joke man. She absolutely slayed this. I love Taeyeon but I have to give this one to Yi Lin and Chen cuz they're wonderful

i really like this song Chen ver. :x listen his voice,.. it's so beautiful :))))

CHEN and Li Yi voice very touchingZhang Li Yi sound such like an angel ♥♥ SM keep her a long timeㅠㅠ

Chen's voice!! so awesome and amzaing!!! omg i love him so much!!! and yeah of course she's very talent

His voice is amazing. 倩倩加油！

The vocal control from Li Yin at 1:14 just kills me every time.

Love ZhangLiYin voice!!!! Perfect duet!!! Chen and LiYin are the best!!!

This is why I love chen so to the mix xxxx chen forever xxx

I really love Zhang Li Yin voice is so beautiful just as same Chen's voice

Liyin no matter how sm treats you, you are still diamond. You always shine!

Standing ovation and slow clapping for Chen & Zhang Li Yin's performance - it's a rare thing and truly worth applauding when artists can sound even better live than their CD recording. I'm so glad first Miracles in December and now S.M. The Ballad gave Chen a chance to show off his incredible vocals; such power, range and control, but above all truly gorgeous to listen to. Golden voice ftw!

Li Yin! Amazing voice!

i love you Chen

Chinese version is always with expression and the lyrics makes the song feel deeper ;)

Wow!!! ZhangLiYin's voice and Chen's voice are fantastic...perfect 👏👏👏👍

Best performance. I'm amazed that she didn't use her ear piece on her first performance. What courage and skill. Just one word "amazing""

Definitely my favorite version. I hope Chen and Li Yin can do more work together in the future! They sound so beautiful together. :)

I'm like dying from all the feels! THIS IS PERFECTION! I remember when Zhang Li Yin first debuted and she was heavily criticized for her live and lack of voice control. ZLY has come a long way and she sounds AMAZING! I love their performance the most!

I am absolutely in love with this version...Zhang Liyin's voice is simply mesmerizing and hopefully she will reach a new height in her career soon. I'm sincerely hoping that her appearance on the Chinese version of "Immortal Song" will open new doors for this amazing singer. Btw, Chen's pronunciation is spot on and honestly, how can you not love this guy?

I like this version better than the korean one.. that woman's voice gave justice to the song...

As a native Chinese, I can tell you that Chen's has almost no absent in singing!! He sings these chinese words so perfectly!!! That must be tough!!!

i'm just really glad that chenchen is trained to sing in mandarin (he's korean of coz he can sing korean well) he gets more opportunity if can sing in different languages :) so proud of him~ i can't stop replaying this song over and over again. liyin's singing skill was already proven long time ago, just that she has been so underpromoted. i seriously get goosebumps from this version coz it's too touching!! well done jongdae+liyin!!

Their voices blend together so beautifully! Love it
