Hi guys

Hi guys :) I'm from US and I'm getting help from my friend who knows korean a bit to log in, but she says she can not help me with writing. I like exo, and I really want to know about wu yi fan and lu han thing. Other exo-l s have so many different opinions about that. Can anyone explain to me? My friend told me that she got lots of stuff related to kpop singers from this site. Thanks :)
