Secret Heiress Sienna's Destined Heir

Sienna, the true heir of the Vale family, disguises herself as a shallow, money‑oriented girl to escape an arranged marriage and moves into the Blackwood mansion. She intends to provoke the four Blackwood heirs into calling off the engagement. Yet she unwittingly reveals extraordinary gifts in racing, tennis and academics. Plotted against by Camille and Eloise, Sienna gathers evidence to fight back while concealing her identity. The cold eldest brother Damian sees through her mask and falls for her true self rather than her status. In the end, Sienna unveils her heir identity, breaks free from being a bargaining chip, and builds a reciprocal relationship with Damian, side‑by‑side running the two powerful families.
