Joo-a, who lived alone with her new father Hail, is worried about Hail’s nephew Do-jin, who has been living with her for a while. This is because Do-jin seems to have noticed that the tsunami and his own relationship are related. And for some reason, young Do-jin is increasingly attracted to him. Then one day, Joo-a is having an affair with another woman, and she asks for sex without knowing that the tsunami has come. The tsunami’s stamina couldn’t survive. Joo-a, who waited impatiently in front of the emergency room, was relieved to hear from Do-jin that fortunately there is no harm to her life. That night Do-jin asks Joo about his relationship with the tsunami. Joo-a tells Do-jin all the facts because he believes that the relationship between the tsunami and himself is no longer hidden. And Dojin also seduces and engages in sexual relations, asking if he’s not mixed with a drop of blood.
