Atsumu wasn’t exactly the best roommate. He was incredibly messy and didn’t pick up after himself at all, that made him incredibly annoying.
It was also really annoying when you had to reminded him 20 times a day to shower and do basic hygienic things. you really couldn’t stand it when he was filthy and messy.
It kinda made you feel like you were his babysitter. Like you were supposed to be taking care of him and making sure that he was doing everything he was supposed to.
But Osamu had warned you before moving in with Atsumu, he warned you that it was like taking care of the puppy dog.
You’d have to feed it and bathe it and make sure it was up to Health. You had to make sure everything was proper. literally just like having a puppy to take care of..
But this is what you signed up for. It’s not like you could randomly just move out or just randomly kick him out of the apartment.
