Kenji was born the second son of three brothers. From her mother, Natsuko, she had the impression that she was an untouchable child. In the spring of one year, my older brother got a job and lived alone, and my younger brother enrolled in a boarding school. The father was assigned to work alone, and his life changed in a hurry, and Kenji and Natsu began to live together with this mother and child. The house, which was lively, suddenly became quiet, and Natsuko felt 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.
