now that he knows he can't use bts for clout he's moving on to leech from somewhere else.... sad

That’s not fair. Music is universal, western artist collabing with kpop artist just spreads more awareness all around

He doesnt need anyone from kpop for clout. He's just being appreciative of a performance if his song.

Perhaps you don't know who this is... He is part of one of the biggest boy bands right now that Korea put together... He doesn't need BTS or Charlie to get famous because he already is... and you cant seriously reference his friendship with BTS as using them... These boys were friends long before any of them made it big... Their friendship was always there... Just because its in the limelight now doesn't mean its a facade to get more popular...
