Ai was born as a daughter of a restaurant. Rie's mother rebuilt the restaurant, which had been in the red due to financial difficulties. Perhaps he didn't like it, his father raised his hand to the child and his habit of drinking got worse. I don't get along well with my father, but I love my mother. Even after going on to school and moving to Tokyo, Ai and Rie stayed at the inn and fostered love that went beyond family love.
