Fifteen years after their iconic romance changed K-drama forever, Gu Jun-pyo (Lee Min Ho) and Geum Jan-di (Goo Hye-sun) return—older, wiser, but still deeply entangled in love’s trials. Now married and living in Seoul’s elite circles, their relationship is tested when Jun-pyo’s long-lost half-sister, Seo Hana, emerges, seeking revenge for a family betrayal. As Hana infiltrates Shinhwa High’s new generation, a new F4 is born—flamboyant, rebellious, and clashing with the values of the original group.

Meanwhile, Jan-di, now a successful doctor, struggles to protect her son, Ji-hoon, from the shadows of his father’s legacy. Past wounds resurface when Yoon Ji-hoo (Kim Hyun-joong) reappears with secrets that could shatter their world. Featuring lavish sets, emotional reunions, and heart-pounding confrontations, Boys Over Flowers Season 2 delivers nostalgia and fresh tension, mixing teen angst with mature drama.

Will love endure the weight of legacy? Or will history repeat itself in heartbreak?
