Sure, he made the decision. But one day he's an extremely powerful hero, the next day he's back to being quirkless. How do you think everything went after that day? Sadness for a couple of weeks as he adjusts to his new (or rather, old) life? What about school. Can he even continue being part of Class A now that he doesn't have any quirk. Did he lose his hero license? Does he continue muscle training for general strength? What do you think happened during the time skip?
