The reason I want to speak Korean language is to be able to understand the true feelings of kyuhyun voice when he sing. Even I don't understand the lyrics I'm so into this guy voice. It's rare, generations after generations will listens his songs.

The thing with Kyuhyun, he can effortlessly perform a duet with someone because he controls his voice well. He knows when to belt and know when to let his partner take over. He doesn't go over the top especially when he knows it's a duet... that two people should stand out, not only one. I didn't choose wrong when I chose him as my ultimate bias. I'm thankful he got me into this beautiful world of KPop. If it weren't for him, I wouldn't have been an ELF.

Kyuhyun's voice gets me every single time 😍😍😍

coming back here after kyuhyun singing this song in njttw7

Kyuhyun's voice is so relaxing

That was such an abrupt ending!! I was so into the song and then BAM. Heart attack.

Kyuhyun voice is magic .

Kyuhyun's voice is pure gold! He has an unique voice among all artists thats why he is my favourite Korean singer, well deserved title "Prince of ballad".

I was so into it and then they didn't upload the full version grrrr...This is so great, their voices sound so good together. I'm crying

the best If It Is You cover i've ever heard. No wonder, it is Super Junior's Kyuhyun, one of the best (if not literally the best) male vocalist in kpop industry.

역시 실력파 아이돌,,, 멋져,,,,,

Kyu ❤❤❤

Kyuhyun and his partner are very greatㅠㅠ love their voice

신서유기 보고 들어온 사람!..

my kyuhyun`s voice is so beautiful ,my sweet heart is so cute "احبك يا عمري "

Kyuhyuns voice is so heavenly, back in the early days I used to dislike him because I feel like he is taking over ryeowook’s and kibums place in suju as a maknae but now I love him and he is my bias now 💙

Kyuhyun and Rosé singing the same song. So much feels

규오빠 목소리가 진짜 조아 ㅠㅠ 파트너 목소리과 진짜 어울리지 ㅠㅠ 풀영상을 어디?!?!?!?!

THIS IS DEFINITELY THE BEST COVER OF "IF IT IS YOU" EVER.
