15!skk was sitting in the rubble after a long mission, waiting for the extraction crew to come while Chuuya is smoking a cigarette to calm his nerves.

He looks so cool, Dazai thinks and mentally slaps himself, stop thinking like that.

Immediately, he reaches into Chuuya’s pocket and takes the pack out of it.

Chuuya gives him a side-eye and clicks his tongue, but still, hands him the lighter as well.

Dazai has never smoked before... he just wants to feel included and "be cool" for chuuya.
