Kunikida is your boyfriend and you(dazai) have some incecurities with your body and its scars and past traumas.

Kunikida came back from work and saw dazai shirtless only wearing shorts...

"Welcome ba-.." you said but he cut you off by sitting you on the couch and started kissing your scared legs.

"You're perfection..." Kunikida said while still holding your(dazai's) legs.
