My Billionaire Sister

Adam, the Landon heir who has lived away for 25 years, is set to marry Sophia Miller. On their wedding day, a “cleaning lady” bursts into the reception — she is Vera, head of New York’s elite aristocratic clan and Adam’s biological elder sister. Sophia’s gold‑digging family publicly humiliates Vera and pressures Adam to disown her, while they secretly court Dawson heir Brian. Seeing his fiancée’s true colors, Adam calls off the wedding, recognizes Vera, and steps in as Blue Bay Group’s new president. He brings down Sophia and the Dawsons, then meets Grace Grant and finds genuine love. His cousin Carl plots repeatedly to seize the inheritance, even trying to murder him. Adam foils every scheme, exposes the conspiracy, claims his place as the sole Landon heir, and wins both career success and love.
