Ms. Meguri, a seemingly ordinary housewife, meets a man online and shares her secret about taking out a loan without her husband knowing. In return for his silence, she agrees to go on an affair trip with him. They spend three days together, during which he gives her fifty thousand yen. To hide this from her husband, she lies and says they went to an onsen hotel. Although initially hesitant due to his lack of action, she begins to trust him more after some time passes. However, things take a turn when she drinks a sleeping pill-laced beverage and passes out. When she wakes up, she finds herself bound tightly with rope, unable to move freely. Her captor smiles menacingly and declares, "Well, let the fun begin!"
