ROE-391 At home where everyone else has left, I spend my days of play with my mother.

Kenji was born as the second son of three brothers. His mother, Saki, gave him the impression that he was an easy child to take care of. But one spring, his older brother got a job and started living alone, while his younger brother enrolled in a boarding school. His father was transferred away from his family, and life changed drastically, leaving Kenji and Saki living alone. Their once-bustling home suddenly became quiet, and Saki felt a sense of loss. Seeing his mother's behavior, Kenji regretted always worrying about his siblings.
