Everyone in the Port Mafia knew Dazai was a bit.. you know, he usually self - harmed after just a minor convenience. Yes, people may know loads about him, but Chuuya sees right through him.. Dazai tries to lie in front of Chuuya? Chuuya can see right through him.

Here Chuuya was, drawing stars around Dazai's scars, Dazai was even comfortable enough to take his bandages off in front of Chuuya, he did really trust Chuuya after all..

"You really gotta stop cutting.." Chuuya sighed, his voice not matching his soft actions.
