It is a family home where the whole family was nested, and it is a daily life of incest that spends time with my mother. Yoshimi YASINO

Tatsuya was born the second son of three brothers. According to his mother Yumi, he was a quiet child who did not assert himself. One spring, he found a job and lived alone, while his brother entered a dormitory school for sports recommendations. His father's life changed rapidly when he was sent to work alone, and his mother and son began living together. The bustling house suddenly becomes quiet, and Yumi feels a sense of loss. Seeing such a mother, Tatsuya felt an unspoken bond and tried to regain the love of her mother who could not monopolize until now.
