Which member seems to be a close friend of your bias?
Sometimes it's obvious to tell like in BTS, V and Jimin are besties, and in TXT, Yeonjun and Soobin seems to be the closest friends. But I don't think I can tell about Minho (SHINee) and Kai (EXO). TVXQ only have 2 members so there's nothing to talk about them.
(Note - Bolded names are my bias in my fav groups)
