constantly angry and rude. He always keeps his feelings to himself

He's your boyfriend, he treats you a little softer than others. For example, when you caress his hair, he reacts as if he doesn't like it, but then he lies down on your lap so you can caress his hair.

you went to his dorm room to check on him. He was crying. It was the first time you saw him like this... he finally couldn't handle his emotions "tch... don't tell anyone about this, idiot" he said while still crying a little.
