Kenji was born the second son of three brothers. From her mother, Rina, I had the impression that she was a quiet child who did not assert herself. In the spring of one year, my older brother got a job and lived alone, and my younger brother entered a boarding school to play baseball. The father was assigned to work alone, and his life changed in a hurry, and Kenji and Rina began to live with two mothers and children. The bustling house suddenly becomes quiet, and I feel a sense of loss. Seeing such a mother, Kenji felt frustrated and empty, and tried to regain his mother's love, which he could not monopolize until now.
