A young woman arrives in Tokyo for a two-week summer program at a prep school, excited to live alone for the first time and work toward her dream of getting into her first-choice university. She had never imagined how different the city would feel once she actually stepped inside — and now, as she settles into her new life, she's not the only one who's noticed her arrival.
Her father, who has been waiting for her, is not exactly thrilled with her presence. He’s been living alone for some time now, and the idea of someone else coming into his space — especially someone who's so enthusiastic about life and study — is a little overwhelming. But as the days go by, the tension between them grows into something more intense.
At first, it's just small arguments about cleaning, the state of the apartment, and the usual things that come with living together. But soon, the conversations turn into something more — something that starts with a little bit of teasing, then escalates into something much more physical and emotional. The father, who had always been strict and a little gruff, begins to show a different side of himself — one that's passionate, playful, and even a little seductive.
As the days pass, the woman finds herself caught in a whirlwind of emotions — frustration, excitement, and a deep sense of connection. The apartment becomes a place of both tension and intimacy, where every argument, every touch, and every moment together brings them closer. The father, once a distant figure, now becomes someone she can't ignore — someone she starts to look forward to seeing.
With every passing day, the bond between them deepens, turning what was once a simple summer program into an unforgettable experience — one that will stay with her long after she leaves Tokyo.
