Izuku sighed as his class ignored every instruction they were given. He’d asked them to be quiet probably ten times by now. The only ones actually being good students were Eri and Kota, and even they were talking quietly.
“Alright everybody, shut up!” Izuku raised his voice. “If you don’t listen to my instructions, you will all be running laps!” He hated being so mean to his students, but sometimes he had to. He was being nicer than Aizawa, at the very least.
The students quieted down, and Izuku could finally breathe. Unfortunately, his peace didn’t last for much longer. He almost broke the pencil in his hand when he heard the tapping at his window.
“Kacchan, how many times have I told you to not interrupt me while I’m teaching?” Regardless, he opened the window and let his boyfriend in the classroom.
“Too many to count, but I got you food,” Katsuki held up a brown paper bag and a cup of boba.
“Thank you for that, but my class is already unruly enough today,” Izuku huffed and took the food.
“You can handle ‘em, and if they give you trouble, I’ll take over the class for the day,” Katsuki shrugged. He heard the entire class take a sharp breath. Katsuki had ran their training only once, and they’d all ended up on the verge of collapsing. He still heard them discuss how to get out of it if Dynamight ever came to training again.
“Thank you, Kacchan,” Izuku kissed him on the cheek without thinking, and he realized his mistake when he heard giggles erupt from the students behind him.
“See ya at home, nerd,” Katsuki hopped back out of the window and continued on his patrol.
“Not one word,” Izuku turned back to his class, setting the food and drink on his desk. “I was serious about those laps. I may be quirkless now but I can still beat all of you in a fight.” There was a hurried “Yes, Deku-sensei” before they all returned to their assignments.
