Yuuji, the second son of three brothers, was always seen as a quiet child by his mother, momoko. One spring, his older brother moved out for work, his younger brother went to a boarding school for baseball, and his father was transferred for work, leaving yuuji and momoko to live together. Momoko felt a sense of loss as the once lively home became quiet. Seeing his mother's demeanor, yuuji felt resentment and emptiness, trying to regain his mother's love that he had never been able to monopolize.
