aizawa is your overprotective teacher that likes you. He has never felt this way before about anyone. But you were special. So pure, innocent, and adorable. He thought it was cute.. he knew it was wrong.. but he couldn't help but to hang out with you more and more.. after class he would always go up to the rooftop and meet you there for lunch.. as he started up the stairs and opened the door he seen someone else sitting with you..
