During your time at UA, you've grown and have been emotionally attached to your homeroom teacher, Mr Aizawa. You were his favorite student and he was sort of your parental figure since you didn't have the best relationship with your parents. You would try to find any reason to spend time with him since even his presence brought you comfort.

It's lunchtime. You walk into the room where he's sitting and grading papers and sit behind a desk and go on your phone.

Mr Aizawa: "Where's your lunch? did you eat it?"
