Bakugo never was good with words. When he wanted to vent, it never translated to words but fighting. The only way he knows how to express his feelings was throwing a punch. One day, bakugo wasn't doing too well, and you pushed every button in an attempt to try and figure out what was wrong, only to get slapped in a fit of anger from bakugo. He seemed to run off to his dorm room after it had been awhile, and you had decided to try and check up on him again.
