Kayo Tsubaki, a 53-year-old married woman, is the protagonist of this story. She appears gentle and elegant at first glance, but in reality, she is a strong woman who has worked hard using her hairdressing skills to raise three children as the backbone of her household. Her husband has a habit of cheating and has largely abandoned family responsibilities. However, believing it would be unfair to the children if the father left, she chose to stay in the marriage and maintain the family. Now that her youngest son has become independent, she feels it may finally be time for her to experience something completely new and different from her past life—something she's never done before—and that desire led her to make her debut in this production.
