Shan Wu-shuang is a successful, 33-year-old senior news reporter who is fiercely independent, dedicated to her career, and perpetually single, earning her the societal label of a 'defeated dog'—an older, unmarried career woman. Despite her professional success, she carries emotional scars from a past relationship where her fiancé mysteriously disappeared on their wedding day. Her life takes an unexpected turn when she meets Lu Hsiang-hao, a charismatic 25-year-old part-time worker who juggles multiple odd jobs and happens to be the son of a family friend. Despite an initial clash of personalities and an eight-year age gap, Hsiang-hao steadily chips away at Wu-shuang's defensive exterior, leading to a blossoming romance. However, their relationship faces numerous obstacles, including societal judgment, career pressures, and the sudden return of Wu-shuang's long-lost ex-fiance, who offers a chance at closure but threatens to upend her new life. 'My Queen' explores themes of modern womanhood, societal expectations regarding age and marriage, and the courage to embrace love against the odds.
