One time, during a prolonged break from school (1 month long due to reasons students weren't keen enough to obtain), Izuku was playing truth or dare with Denki, Kirishima, Todoroki and most of the Class' girls, Izuku got dared by Mina to ignore Katsuki for a week.

So, Izuku did it.

Today was the first day of the challenge: Monday.

Most of class 1-A spent their time in the common-room, idle chatter filling it, striking new games every now and then.

Izuku, while usually not a morning person, was interacting with them like he tottaly did not wanna go back to sleep and be a rude mess.

He was abruptly shaken from his thoughts when a tall figure loomed over him. He knew who it was. ”Izuku,” the voice rumbled near the grenette's ears, a chill running up his spine. ”Are you grumpy?” Katsuki added with a small chuckle escaping his mouth.

Though, Izuku tottaly ignored him. He wasn't able to talk— the dare..the dammed dare..

Izuku was so gonna get Mina back for that dare— but now he had to suffer through the challenge of giving the 'silent-treatment-to-boyfriend" week.
