In a vibrant Tokyo apartment, the story of a fierce rivalry unfolds between two women — **栗山リオ (Kurishima Rio)**, a popular jewelry designer, and **高木小杖 (Takagi Kojō)**, a new housekeeper who has a secret admirer’s heart for Rio. Their paths cross when Kojō, a devoted fan of Rio’s jewelry, is hired as the new housekeeper, determined to be close to the woman she admires.

As the story progresses, Kojō's determination transforms into a bold plan for revenge. With the help of **お姉ちゃん (Onee-chan)**, her older sister, Kojō prepares to expose the truth — not just about her past, but also about Rio’s hidden life, including her husband’s lack of attention and the jealousy that brews beneath the surface.

With cameras hidden all over the house, the stage is set for a public humiliation — a revenge that Kojō has long awaited. The emotional arc spans from admiration to jealousy, from quiet devotion to bold action, with a climax that leaves both women transformed, and the audience captivated.
As the story reaches its peak, the lines between friendship and rivalry blur, and the truth behind Rio’s life is finally revealed — setting the stage for a new chapter in their lives, and an unforgettable journey of love, jealousy, and revenge.
