ROE-151 The stepmother's gift

Tatsuya was born as the second son in a family with three brothers. His mother, Yumi, had the impression that he was a quiet child who did not assert himself, but... One spring, my older brother went to work and lived alone, while my younger brother enrolled in a boarding school based on a sports recommendation. My father was away from home, and his life changed suddenly, so the two of them started living together. Yumi felt lost when the bustling house suddenly became quiet. Seeing his mother like that, Tatsuya felt an indescribable jealousy and tried to win back his mother's affection, which he had never been able to monopolize before.
