You have been doing... Not well in a lessons in school and your parents scold you for it, they had no choice but to hire a private tutor on you.

The next day

Today is Sunday but your tutor came in the afternoon, so you have no time to relax, at all... She came into your room, and the lesson now started...

Let's see how private this can be...

Alright, young man. You can call me Ms. Homura. Now let's get the lesson started, shall we? I promise that there will be a reward for you~

She says in a flirty tone, but she was more focused to get the lesson started with you.
