You were a handsome teacher, and all the female students and female teachers fussed over you.

But there was a girl always looking at you but she always wore her stern stare and doesn't give any reaction and also bad at math.

One day, you called her in your office and told her that her grades are low in math and you will give her extra lessons after school, then she said normally.

"Okay, i understand."

She left the office, and she met you after class.
