I wouldn't mind a K-PC collab tbh both are already pop music in it's purest forms, PC music just adds more unconventionality. It would also probably be a good way to get at least a slightly wider western audience
NoT Super Natural tho. I like Danny but he could've done better
EDIT: I just remembered Li Yuchun/Chris Lee had this, Chinese but I'd be here for an idol doing this
I'm going to ignore the Super Natural shade and just say that Real Love / Only You is very cute and we definitely need k-idols to follow suit.
