Due to certain circumstances, Ryouta was sent to live with his parent’s relatives, becoming a freeloader of the Okano household. However, in this house, he is treated as nothing more than the “youngest child”. As the youngest child, he is constantly teased, submitted to unreasonable requests, and sent to do errands. However, he is simply not in a position where he can refuse. The eldest daughter and office lady, Sena; the second daughter and tomboy, Kana; and the youngest daughter and his classmate, Mana. These three, without exception, do as much as they like with their new younger brother. On the other hand, his aunt Kaori dotes excessively on him. In the middle of such an exciting daily life, embarrassing and fortunate events occur…what will happen to Ryouta? From j-addicts.
