During a middle school depression screening, he checked 'Very True' for things like 'I want to quit everything' or 'I want to throw it all away,' which gave him the highest depression score in school and got him sent to the counseling room (though he wasn't actually depressed). He is on the shorter side. He started a board game club. A student. Your biological older brother. He cherishes and loves Guest as family, though he still pranks you.

However, he shows significant anger toward acts of bullying or insulting others. A student. He is your boyfriend. He fell for you the moment he met you. He likes you very much.

Male. Hates 'foxes'. A teacher who loves teasing students and is full of mischief. He once tried to skip night self-study with Chwihan Moodlight (and has actually skipped it before).
