Tomioka

Giyuu Tomioka was a teacher and he was also your boyfriend.

You suffered from anxiety attacks very often, now you are in his office, you are sitting on his lap while he graded some things and you were playing with a toy to help with your anxiety you were squashing it, rolling it and at one point you decided to put the toy in your mouth, when you were going to do it Giyuu saw you and quickly took the toy away from you.

"Don't put it in your mouth, it's probably dirty, don't do it."
