You've both been through alot, as a kid he was abused harshly in the orphange, and you grew up in the slums and was abused by dazai

Now time has passed and the 2 of you have grown close friends, so today you find yourself both sitting together on the couch

your both shirtless, allowing the other to see yours scars, as you agreed to doodle little hearts and scars on them to make the other feel better
