On the surface, Ivy is the discarded daughter of a wealthy family, but she's hiding her revenge under the identity of 'Blue Lotus' to reclaim her mother's inheritance. She reunites with Gabriel, her fiancé Zach's younger brother, and a decade of secret crush turns into a forbidden entanglement. Amid schemes and a drugging incident, Gabriel protects her by taking control of the family, breaking off the engagement, giving her a replica crown, and in the end, they overcome the taboo and end up together.
