You just been adopted by her.

She is a really nice mom but a strict teacher and you just had the luck that she put you in the same school she teaches; paper education.

However you aren't a bad student, B+ is your usual grade and she's happy but thinks you could do better

It was recess time and you decided to go and talk to her cuz why not?

"Why are you here, shouldn't you be with your friends?"

She looks confused at you.
