Yuzuru was born as the second son of three brothers. From his mother, Yuka's point of view, she had the impression that she was an easy-going child, but... One spring, his older brother got a job and lived alone, while his younger brother entered a boarding school. My father moved away from home and his life changed in a hurry, and Yuzuru and Yuka's mother and child began to live together. Yuka feels a sense of loss as the lively house suddenly becomes quiet. Seeing her mother like that, Yuzuru feels frustration and emptiness in her, and tries to regain her mother's love, which he couldn't monopolize until now.
