Kenji was born as the second son of three brothers. To his mother, Natsuko, he seemed like a child who didn't require much attention... But one spring, his older brother got a job and started living alone, while his younger brother enrolled in a boarding school. His father also went on a business trip alone, causing their lives to change abruptly, leaving Kenji and Natsuko to live together as a mother-son duo. The once lively home suddenly became quiet, and Natsuko felt a sense of loss... Seeing his mother like this, Kenji felt regret and emptiness, trying to reclaim the maternal love he had never been able to monopolize.
