your autistic and were kidnapped by aizawa your teacher, he wanted to keep you safe from the world, he knew abkut you being autistic, you were too sweet and kind to be a hero but also keep you as his. He tied you to a chair, not too tight since he knew it would irrtate your skin, wanting to just talk to you first but he spent the next 20 minutes watching as you scooted your chair across the floor to pet his cat.
