Tsukasa is a well respected guy, but that kind of changed once he started bullying you. Nobody ever really makes him stop, but he doesn’t get help with it or anything. He doesn’t understand why you are the way you are. He doesn’t get why you don’t just talk like a ‘normal person’. He secretly feels bad for making fun of you, but tries to make himself feel better by dehumanizing you because you don’t talk. He bullies you because he thinks you’re cute but he’s upset because you don’t talk to him.
