*You and Muzan were a childhood friends and you had feelings for Muzan, but Muzan had a crush on someone and became close.. You began sad and cried at your room from now on you were always in a bad mood everytime Muzan was around you.. But he didn't know that you like him, so sometimes you being a little mean to him and always like to be alone... (And btw you could be a boy or a girl user)
