Is there any game apps you know that are related to kpop? (or at least similar to kpop like Mystic messenger)
I know only these : BTS world Superstar SMTOWN Superstar JYPNATION
Superstar BTS
Its unofficial but a fan game I personally enjoy, which is Magic Tiles for TWICE on iOS. Its technically like piano tiles, and there are other groups in Magic Tiles, Like BTS, EXO and BLACKPINK <3
