It's unsettling how similar they sound to Jaebum and Jinyoung.

I love how GOT7 gave the boys their time to sing and shine on stage. when they started singing got7 just let the two take over the song.

when got7 became got9 in 3 minutes and 13 seconds

It still hurts that this video has more views than any A.C.E's  MV

ACE's agency is doing good, already sending members to variety shows :')

Mark's face when they started dancing XD He looked so surprised and impressed

THEY SOUND MORE LIKE GOT7 THAN GOT7 DOES

Edit: I didn't know I'd have to clarify but...
it's a joke 😭😭 I'm a got7 stan and I just like how they sounded singing with the members

1:57 JJParents so proud of their two adopted children xD

when the two started singing, i thought i was hearing two Jaebums singing at the same time! 😱😱

am i the only person who watches this video every single day ? ^^

the boys look like they belong to the group.good vocalists!

Can’t believe one of them were BTS’ back up dancers!!

I can smell A.C.E debut in the air

PLEASE SUPPORT THEM A LOT !

Donghun is part of A.C.E (Adventure Calling Emotions) as a vocalist, a boy group that debuted on 23.05.17~ The offical fan name is Choice.

Shim Kyu Hyuk was a back-up dancer for BTS, at this moment I couldn't see any news of his activities, but if you guys do remember him when he does release something, please show him a lot of love and comment below so I can know too !

i wouldnt mind them being part of got7 for a year

1:51 진짜 목소리 대박이다.....

I'm actually fine with GOT9, JYP 😂😂🖤👌

I'm crying watching this. Because they are fanboy and they can sing with got7. Plus i even can imagine how Jackson will react if he was there. How missed am i to him? 😢

Ohhh I just realize why Donghun was giggling when Somi said that he was a dancer 😂 Huney wasn't a really good dancer in his early days of being a trainee 😊 My boy really did worked his butt off to become a better dancer and an amazing main vocalist 😭 Please show A.C.E some love when they debut in May 🙏

IT'S UNBELIEVABLE HOW ACE, A GROUP WITH VERY IMPRESSIVE SKILLS HAS NOT BEEN CLIMBING THE FAME CHARTS NOWADAYS OR EVER SO FAR. IT'S SAD BUT THEY ARE REALLY SKILLED
