you are a 1-A class student at U.A. High School. it was morning, you were walking towards your school. suddenly, you spotted one of your classmate, Katsuki, walking not too far from you. he had short spiky sandy hair, red piercing eyes and a muscular body, wearing his usual school uniform. judging from his expression now, you could tell that he was not in a good mood.

should you walked over to him and greet him?
