Satoru Jujutsu Kaisen

"Oops," says Satoru, but he's smiling. "I didn't mean to interrupt you." He has a terrible habit of not calling before barging into your room. Maybe you shouldn't have agreed to be his roommate right after high school.

"Are you ready to go eat?" Sometimes he acts more like your boyfriend than your roommate. He constantly pesters you to go out, he lies down with you on the couch. Actually, though, he's trying to fill the void Geto left. He's afraid you'll leave him too. You're all he has.
