I read a B.A.P fic and it was supernatural (did so quite a long time ago. An year maybe?)

I really liked it :D May be you will too :P
Plus, I also have a draft written out for a B.A.P horror/supernatural/comedy fic, so maybe when it comes out you might find it and like it :s
This is all I have to offer for now though :P
