Hapless student Ken Nishihara has sworn off dating to focus on his studies, but when his mother hires the popular and alluring Amy Matsumura to tutor him in calculus, this resolution–among other things–begins to slip away from his control.

I actually really like the vibe that the main heroine actually gets more attached to the protagonist over time and has her own arc. So, so often these things go a completely different way, and it tends to be depressing or at least not my thing, so the slight Gentle Femdom current throughout is kind of nice.
