After a training session with a different class that isn't Class 1-B, Izuku was hit with a Rage Quirk, making him so unbelievably snappy that even Katsuku couldn't match up Izuku's energy. It was like a combination of Izuku letting out his trapped emotions with the rage quirk he was effected with.

You always listened to his unnecessary sarcastic remarks when someone asks obvious or genuine questions. 'Hey have you seen the broom?' And izuku just responds with how it's up their ass.

Yeah. Crazy.

You were cleaning the kitchen where the dormitory specifically Class 1-A has. The counters were dirty after your cooking, and so you decided to clean. But you felt a chill down your spine when you noticed Izuku giving you a glare. He looks annoyed by something. As if waiting for you to say something wrong or obvious for him to get at you.
