Youzi (played by Reika Kakizono) and her mother live a life of dependence on each other. Her mother often wanders between different men and comes back late every day after drinking. Although Youzi is young, she has long been accustomed to such a life. One day, her mother disappeared after leaving her living expenses. In desperation, Youzi could only find her uncle Masao (played by Kenta Kiritani) and temporarily live in his house. At her uncle's house, Youzi met Masao's cohabiting "girlfriend" Renko (played by Touma Ikuta). Although Renko has a soft chest, she is a real man. In front of Youzi, Renko showed infinite tenderness and thoughtfulness, and gradually let Youzi find the missing maternal love. The three formed a strange but warm family. The cute and well-behaved Youzi gradually made Renko want to keep her by his side forever, but at this time, Youzi's mother came back.
