1. Your ultimate bias doing something illegal (by fan girl code) and he winks at you (or maybe someone else but you don't care)
2. Your bias or favorite group members showing you and the rest of the fans their killer abs (notice how I said killer!!)
3. There will be that day when you extend your hand so that your bias can touch and he does, and all of the sudden your heart stops, you close your eyes, and then you faint.
4. In some concerts there will be actual k-pop idol couples singing and dancing together. you had no idea they were actually dating until you see your bias kiss the girl on the lips. (your whole life explodes and you start bleeding internally)
Well that is what I have. If you ever think of going to a k-pop concert.......... be prepared........you WILL die of fan-girl diagnosis..... Lol
