TheNaveOfCharlemagne Lmao I wasnt into kpop but ACE me become into kpop so yeah thats how amazing they are. I recommend BTS I Need You cover (shows off their dancing skills) and STAY, Playwing with Fire by Blackpink and Last Dance of Bigbang. They have so many covers you can check out but the ones I mentioned made me stan them. And u can watch their auditions in The Unit (Jun and Chan) and Mixnine ( Wow, Donghun and Jason) since mixnine introduced me to ACE. And the most amazing part, Chan will debut in The Unit while Jason will debut on mixnine. And another interesting is The Unit debut group Main vocal is Chan and Mixnine's main vocal is Donghun plus the main dancer is Jason. All from ACE and lmao idk what will happen once they debut since ACE got all the main positions. Hahaha it's kinda rare tbh and yeah they're talented and glad they are slowly getting recognize by their talent and not because they wore hotpants during their busking and debut era. 😂
