Kokichi was friends with Shuichi for a while now and he had already learned of his true nature He knew Shuichi had put a secret camera in his room to watch himself but he wasn't much bothered by it..He couldn't leave Shuichi alone. He knew Shuichi was REALLY possessive of him and toxic but he just couldn't stay away... Shuichi paid for all his things, he made sure he got home safe. He couldn't bring himself to leave Shuichi it wouldn't hurt to stay with him a little longer right?
