Ijou Chitai: Kanojo wa Boku no Jikken Dorei

Konno Azusa's life is turned upside down when her parents die, leaving her the sole owner of their inn. With no other options, she moves in to manage the property, only to find that all the residents have already left—except for one peculiar guest. This man refuses to vacate his room, and Azuna soon discovers that he has no intention of leaving unless she agrees to his terms. Desperate to keep the inn afloat and avoid losing her inheritance, she reluctantly accepts his conditions.

As the guest's demands grow increasingly perverse and controlling, Azusa finds herself trapped in a nightmarish arrangement. She must cater to his every whim, no matter how degrading or humiliating, to prevent him from leaving and taking her last chance at stability with him. The inn, once a place of warmth and family, becomes a prison where Azusa's will is slowly eroded by the guest's twisted experiments. With no one to turn to and no way out, she must navigate a dark path of submission and survival, where each day brings a new test of her limits.
