I love you, Mom... From the outside, it may just be a sweet relationship between a parent and child. But the love Koji feels for his mother, Miyako, is pathologically intense and twisted. When he witnessed his parents' sex life, jealousy towards his father welled up inside Koji. He couldn't bear the thought of his father's semen being poured into his beloved mother. Unable to suppress his desire to monopolize his mother's love and body, Koji embraces Miyako and confesses his forbidden feelings: "If you truly love me, then do what you do with me, Dad."
