Kenji was born as the second son of three brothers. To his mother, Tsuba, he seemed like a child who didn't need much attention... One spring, his older brother got a job and started living alone, while his younger brother enrolled in a boarding school. His father went on a business trip alone, and life became hectic. Kenji and Tsuba began living together as just the two of them. The once lively home suddenly fell silent, and Tsuba felt a sense of loss… Seeing his mother like this, Kenji felt resentment and emptiness towards his siblings' attention, trying to monopolize his mother's affection.
