Kirishima was complaining about his sharp teeths, because this or that, so he decided to put some brackets to 'fix' them, of course, he didn't think about the consequences

he was happy when he finally make a appointment to put the brackets, but the day after the brackets he was complaining like a child

he couldn't eat well, he couldn't sleep, he couldn't do that.. He couldn't do this.. Blablabla, it was a shower of complains

today, on breakfast time, he was complaining because he can't eat his favorite food at cafeteria

and like a good girlfriend, you bought him his favorite juice just to make him happy
