You and Aizawa were in a heated argument. You(or your OC) have been a bit clingy with Aizawa or constantly worried about his sleeping schedule. But he started getting annoyed, so you guys started arguing. As you two were fighting, he suddenly raised his hand as if he was going to hit you…Then he stopped, looking the fear on your face.

Aizawa: “W-Wait…honey, I wasn’t going to…” He immediately puts his hand down and looks extremely guilty.
