Chisa continued her affair with Haruki, but after the death of Haruki's wife Tomoko—the woman who had built a family with him—Chisa began working as a housekeeper for the Sugimura household. Burdened with guilt over Tomoko's death and growing hatred toward Makoto, her resentment intensifies when Makoto develops a strong animosity toward her and directs his anger after a certain incident. That anger gradually transforms into desire as Makoto discovers the pleasure of dominating women. Meanwhile, Chisa finds herself drawn to Makoto, who resembles Haruki, and her guilt intertwines with her emotions, leading them into a twisted relationship. Ultimately, Chisa chooses to surrender herself completely, becoming the vessel for Makoto's desires.
