miss this squad, cant believe i've been fan of yours for so long already... many things happened during these years. hope to see you guys again :')

They are from So. California. Alan is Vietnamese, David Korean/Vietnamese and Isaac is Korean. (Born in Korea but emigrated to California as a child.)

cityincolours has seriously good voice

holy shit the first guy sounds exactly like Youngsaeng holy holy holy cows. Seriously, if y'all send this to YG, you'll make it big :)

The death note poster in the background

Ahhhh you guys sound good together mostly the first guy he sing just like them :o

You guys are all great. I love how StillNotDavid tried to make it funny with the sign and the calls.

you guys sound absolutely beautiful!

im with stupid hahahah

El tono de Citycolors me gusta suena muy bien

you guys are so amazing...

no matter how many time I left ya, I always come back and still get my heart flutter :)

SS501 ♥

Alan is handsome😄 And his voice is perfect... Can anyone tell me where Isac is?

You all sounded great. Loved it.

Can't wait to hear more! ^_^ I love the voices. Good job. I almost couldn't tell the difference between the cover and the original.

"I'm with stupid" that's priceless!

While I adore this song and recognize that they all have talent, I don't think they're well suited for this song and for each other. Their voices, in my opinion, aren't compatible. Also, this song is supposed to be deep and very emotional, however, it just seemed like you guys were fooling around. The emotion wasn't there. As well as the fact that sometimes the voices were off pitch. However, I am aware that these three are very talented singers. I just suppose this song wasn't right for them. It is not good in my opinion, but I can see that other people like it and I know why. My apologies for disturbing.

You guys are amazing...keep going.. I love you guys

I love this song soooo much😭😭 Memories of Boys over Flowers😭😭😭😭. Tbh you made this song even more loveable❤

All 3 of you are soo cute... and you sing... I don't think my heart can handle this ♥
