Toji Ide, a college student, first met Kyoko Sano in childhood when she served as his live-in nanny and tutor. His frequently absent parents entrusted her with his care until her dismissal after an inappropriate relationship with him was exposed, leaving lasting emotional scars. Years later, their adult reunion reignited a fraught bond, intertwining romance and sexuality with her role as a wet nurse supplying breast milk.

Their volatile dynamic fractured when Toji secretly pursued Marika, Kyoko’s daughter and his classmate. The affair provoked Kyoko’s wrath, leading to his imprisonment and violent punishment. Though he initially acquiesced to her control, his attempt to abandon Kyoko for Marika intensified their conflict.

After Marika vanished, Toji returned to Kyoko, only to learn of Marika’s murder. Kyoko then subjected him to months of torture, sustaining him solely on breast milk while starving him, until malnutrition and injuries claimed his life. In his final moments, he harbored conflicted loyalty, interpreting Kyoko’s brutality as an embodiment of "Absolute Love."

Investigators later uncovered evidence tying Kyoko to the disappearances. The narrative ends ambiguously as Kyoko, armed and defiant, confronts the detectives, their confrontation unresolved. Toji’s story traces a spiral of dependency and manipulation, rooted in childhood trauma and the tangled legacies of his relationships with both mother and daughter.
