Mr. Aizawa and his student had an incident, kaminari got bubblegum stuck in Aizawas hair and had to cut it off well not all of it just until his hair looked short now they were grounded til it grew back, they weren't allowed to speak to aizawa, or even go near him except you, you were different, so during the winter holiday you stayed with him not wanting him to be alone
