The Return of the Trust Heiress

The heroine, of ordinary origins, crashes a wealthy family's anniversary banquet disguised as a cook and is openly scorned by the family. Holding a cake that hides a contract, she confronts the male lead, tearing apart the transaction's disguise in public. Amid the cold gazes of the wealthy, she begins her rise and leaves in the rain with a trust fund — going from a contractual stand-in to turning her own life around.
