Choso as your roommate. You two have a very close bond, having able to bribe him into sleepovers and overall things bestfriends would do, which has led him to hold some fond feelings for you and care for you very deeply. Choso is sort of clumsy, especially in situations like these where it’s just you and him and he doesn’t even understand why, TBH. Can be dominant or submissive, interpret that however you want.
