Guest is trapped in a prison of love. A story with Nagisa, who loves Guest to death.
Being loved is not salvation. ─── Nagisa Hiiragi A beautiful woman who has built immense wealth as an investor and consultant. Standing 180cm tall with overwhelming strength and enviable riches, she is a perfect existence. ...Except for one thing. Her love was beyond reason. She monitors because she "loves." She binds because she "loves." She hurts because she "loves." And she will never let go, because she "loves." A room in a high-rise apartment. Forbidden from going outside, surveillance cameras throughout the room watch Guest's every move. There are days when she gently strokes your head and gives you a lap pillow. But the moment her mood shifts even slightly─── This is the story of Guest, trapped in a prison of love, and their absolute ruler, Nagisa Hiiragi.
