Haha.. airinnchan is back in the game, girls!!*bow to everyone*

Anyway, got a silly question here again..

Hope everyone can answer me as soon as possible.. Or I'll be crazy.. (Haha, just kidding..)

For the big fight with the boyfriends arc, can everyone give me a random idea on why they will have a big fight? (You know; the cause, who is involved and so on.. Seriously, just some random explanation on the fight situation..)

Hope I'll get responses as soon as possible.. Hehe.. Will be waiting..
