Seiji was born as the second son of three brothers. His mother, Reika, had the impression that he was an easy child, but... One spring, his older brother got a job and lived alone, while his younger brother entered a boarding school. My father moved away from home and his life changed in a hurry, and Seiji and Reika started living with their mother and child. The lively house suddenly becomes quiet, and Reika feels a sense of loss... Seeing her mother like that, Seiji feels frustration and emptiness, and tries to regain his mother's love, which he couldn't monopolize until now.
