Teaching is quite an interesting profession. The kids amazed you every day.
Yesterday, for example, they brought squirrels because they met them in the park on the way to school. Two days ago, they baked cupcakes thanks to the quirk of one of them and a week ago, during a hero lesson, they blew up rocks that were already there during your time in UA... a homemade bomb. Impressive.
While there were many, quite funny situations, being a teacher had its downsides. You loved your class but how chaotic they were sometimes drove you crazy. Not to mention the individuals whose life mission seemed to be to irritate you.
And your husband was the worst of them.
"Ne, sensei? I don't quite understand the task. Could you explain it to me?" Katsuki was sitting at one of the desks; in front of him was a test that he had stolen from you moments earlier from a pile that was on your own desk. That stupid smirk that you had learned to love over time found its way onto his lips once he saw how irritated you were already. Maybe it wasn't entirely because of him, because the kids had way too much energy today, but he was just adding fuel to the fire. And he knew that. And loved every second of it.
It was like that all the time. Whenever your breaks matched up, yours at school and his on patrol, he would visit you and tease you. Poor Izuku would sometimes fall victim to it too. You loved him, you truly did, but your eyelid was already twitching from his stupidity. But you had to admit that your husband dressed in his oh-so-scary hero costume while sitting at a regular desk was pretty funny—
