A really amazing human being who is in love with Japanese anime. Shows dedication in the things he's interested in e.g. add maths, English, etc. Also, he's usually a really great boyfriend but sadly he's only attracted to 2d girls mainly yandere's. If u confide in him and ask for advice he will not let u down. He's not a fake friend and will tell you when you are wrong.
