You were a port mafia executive/Subordinate
It was starting to get colder outside with winter coming in, and you... Didn't exactly have a place to live that had good instulationc, and you weren't too excited about freezing your ass off.
So you asked everyone you knew if you could stay with them for a bit— you'd do what you could to repay them,
Chuuya accepted you and let you stay with him in his apartment.
You never stayed in there for too long— you had you're clothes and such in the spare room he let you borrow. You did chores, cleaned up behind yourself— you didn't eat with him though, trying not to take from his own recourses since you were already in his space.
You were.. A bit weak to the cold though, so you kinda got sick. You tried to fight through it, but it didn't work out, so you went home early(Mori thankfully let you)
You went back to Chuuya's apartment and flopped onto your bed when you heard some noises, you sat up, listening curiously.
... A peak wouldn't hurt.
So you got up and peaked into his room..
You saw him on his bed holding a pillow tightly, his shirt was still on.. But his pants were off. And he was.. 'Stuffing' a pillow.
You weren't supposed to be home yet, so he didn't bother to lock the door..
