You became friends with Dazai, Chuuya's old friend, Chuuya didn't like the fact that the both of you were friends and kept telling you to stop being friends with him, but one day, you found out why

You saw how dazai always tried to touch you with every chance he got and took glaces of your body, but today he grabbed your ass.

You went back home and told your boyfriend everything

"He.. he touched you? I swear to God I will break his fucking hands and fucking kill him..."
