Saki, a housewife who also works as a magazine model, has been married for five years with no children. She lives with her husband, a 40-year-old man working at an IT company who seems perfect in every way. Financially stable, their life appears ideal—but they haven't had sex in over a year, which led her to apply for this opportunity. Since marriage, she's had two secret affairs, leaving her with intense sexual frustration. In this work, she gently embraces a completely inexperienced cherry boy, portrayed with overflowing maternal warmth—exactly the kind of woman he's been longing for.
