William, the son of an overseas billionaire, has been working incognito at his girlfriend Seraphina's company to help her succeed, planning to reveal his identity after their wedding. A week before the ceremony, he discovers Seraphina has already used her marriage leave—and listed her male secretary as the spouse. After she dismisses him with contempt, heartbroken William withdraws all his secret support, returns abroad to claim his inheritance, and finds true love with his childhood sweetheart.
