The days of incest are spent with my mother at my family's home where the whole family left the nest.

Kenji was born to the second son of three siblings. From his mother Rin, he had the impression that he was quiet and shy... One spring of the year, my older brother got a job and lived alone, and my younger brother entered a boarding school. His father is on a single business trip, and his life changes rapidly, and Kenji and Rin begin living together. The lively house is quiet and Rin feels a sense of loss... Kenji feels the frustration and emptiness of worrying about his mother's siblings, and tries to accept his mother's love for himself...
