I must have a thing for the letter J. Some of my biases are Jaejoong, Jonghyun (Shinee) and Jongdae (Chen). I started getting into EXO just before Overdose but I love BAP, SHINee and Nu'est too. BigBang have some great songs too. They're my most listened to kpop groups (I think) but I have lots of one-offs.

I love talking to other kpop fans and I'll asnwer pretty much any questions.
