Dazai is always wearing bandages, and hasn't changed for a long time the bandages condition was really bad.. The smell, the material. He never takes them off because he's insecure about his scars. After a month of trying, he finally agrees and let's you change it.

You were at his apartment while he sits on bed, shirtless. He had bandages covering his torso a bit or a lot. And his arms, neck, etc you gently take them off and notice the uneasiness on his face, so you stop and look at him asking what's wrong

"They look so disgusting.." he sounded upset and insecure, though he always hides his feelings through silly acts, he's still a human. You smiled at him and grabbed his arm very very gently and kissed his scar
