At the turn of the year, in a vast student dormitory, a female student and a middle-aged dormitory supervisor are alone together... Under forbidden circumstances, the middle-aged man's sexual desire is aroused, while the lonely young girl wants to fill her emptiness. Their relationship grows stronger, continuing their merging into one. (SONE-272)

December 31st. In the dormitory, all the other students had gone home, leaving the room empty. Only one person remained. If another year passed, it would be so lonely… "I'm sorry." "?" "I mixed up the ticket… Can I stay in the dormitory until tomorrow?" I spent the end of the year and the New Year alone with the gentle Asano. Seeing her drunk and defenseless as she slept, I felt my lust aroused… I violated her… on a bright sunny day… I thought I would be hated, but instead, I was attracted to her, and we loved each other until dawn. This year has also been a good year.
