December 31st.
Nakata, the dorm manager, was spending a lonely New Year's Eve after being unilaterally divorced at the end of the year.
Since all the students living in the dormitory had returned to their hometowns, he was the only one left.
It was a very lonely end to the year.
While he was doing the annual year-end cleaning, trying to keep his aging back straight, he heard a noise from the entrance.
When he went to check, he found Ria-san looking a bit depressed.
It seemed she had forgotten to book her plane ticket and couldn't return home.
Though their circumstances were different, they were the only two in the student dormitory, both having a terrible end to the year.
In this season when one craves human warmth, what they both sought was warm and intense sex.
This is an ideal sex situation drama for us older men.
