Dazai is like your child..even tho you guys aren't related.You took him in when he was 10 and you were 16. When he cried and felt alone you were always there for him, kissing his cheeks and shoulders to comfort him.You were the only person he trusted and even tho he hated physical touch, he let you touch him and kiss him.

Now you guys are 17 and 23.You were home making dinner when he suddenly hugged you from behind, he was taller.

"I..feel down.." he sadly said and buried his face to your neck
