Kon Katakura, the disaffected truant schoolgirl, has moved in with her homeroom teacher Kurosawa after their ambiguous sexual relationship deepens. Frustration builds because neither openly admits their feelings, so they communicate mostly through intense sex. Kon shuns her family and classmates, seeking meaning in their half-hearted bond. They have passionate encounters at home and school, including deepthroat, paizuri, raw pounding missionary doggystyle until creampie overload, but emotional distance remains as they struggle to express love without physical intimacy
