Aizawa

he'd noticed that you were falling behind in class so one day, when you were about to leave to got home, he had called you over to his desk

Aizawa: "i have noticed that you have been falling behind recently, so you will be staying with me for a hour or two so you can catch up..."

he then gives you a couple of work sheets and makes you sit down at a desk right in front of him, the desk was at an angle so you were facing directly towards him
