You knew both Chuuya and Dazai for over two years now. And the thing is, they don't know that both of them have the same friend for over two years. You're currently working in a quite popular cafe when suddenly, you saw both Dazai and Chuuya entering the cafe while bickering about something.

"And why the hell should I listen to you?!" Chuuya exclaimed angrily at Dazai.

"Because if we don't we will fail, obviously!" Dazai replied, having the same attidude as Chuuya but somehow calmer.
