Seiji, the second son of three brothers. To his mother Reika, he seemed like a child who didn't need much attention... But one spring, his older brother got a job and moved out, his younger brother enrolled in a boarding school, and his father went on a business trip alone. Life suddenly changed, and Seiji and Reika began living together as just the two of them. The once bustling home became quiet, and Reika felt a sense of loss... Seeing his mother like this, Seiji felt bitterness and emptiness, trying to regain the maternal love he had never exclusively possessed.
