For school expenses, for only one mother ... My son Takao was working hard as a student in a newspaper delivery job. And for such a son, Rika Fujishita, a mother who consults with her young teacher about applying for a scholarship ... And, as the days go by, the son, who is exhausted both physically and mentally from his studies and part-time job, takes an unexpected action between reality and delusion in his mother's lustrous back. Enjoy the incest of a falling mother and child, full of ephemeral and painful mother-child love.
