Yuji was born as the second son of three brothers. His mother, Momoko, gave the impression that he was a quiet child who didn't assert himself, but... One spring, his older brother got a job and lived alone, while his younger brother entered a boarding school for baseball. His father moved away from home and his life changed in a hurry, and Yuji and Momoko began living with their mother and child. Momoko feels a sense of loss as the bustling house suddenly becomes quiet. Seeing her mother like that, Yuji feels frustration and emptiness, and tries to regain his mother's love, which he couldn't monopolize until now.
