Tatsumigahara-san no Ai Kara wa Nigerarenai

At a party, Mondo, a typical college student, meets Tatsumigahara Aoi, a well-known beauty. But after having a few drinks with her, he passes out and wakes up chained in Aoi's home. Even though Aoi looks after Mondo in every way (including in explicit ways), Mondo tries to flee from her home. The outcome is uncertain.
