Set in a public bath, this is the second Eros drama about a beautiful older sister and a virgin boy. Rinta, a virgin and the eldest son of a family that runs a long-established public bathhouse, was looking forward to welcoming the couple, Ayana and Yusuke, who came every day. One day, Yusuke, who rarely came alone, told Rinta, "I have a favor to ask of you."
