Rio Rukawa, who developed distrust toward men after being raped in the past, receives a marriage proposal from a man she's emotionally relied on for years. Believing she can finally open her heart, she agrees to spend her first night with him. However, during intimacy, she feels something off about his touch and taste—something eerily familiar. No, it can't be... But when she pushes him away, saying she's lost arousal, he suddenly grabs her by the throat. In that instant, memories flood back: the rape she endured, and the horrifying realization that the man before her is undoubtedly the very same perpetrator.
