Savannah Sterling, the sole heiress of the realm's wealthiest family, suffers a brutal betrayal in her past life. Her fiancé Carter Grayson and his adopted sister Lily seize her family's fortune, torture her parents to death, and bury her alive. Reborn on her 20th birthday—the day she was fated to draw Carter's name in a marriage lottery—she smashes the lottery box and auctions her hand in marriage instead.
Mysterious Eastern trade magnate Felix Harrison, who has secretly loved Savannah for 12 years since she helped him as a homeless orphan, bids an unprecedented 1.99 billion gold to win her. Humiliated Carter and Lily kidnap and torture Savannah to force her into marriage. At the engagement banquet, Felix exposes their crimes, ruining the Graysons. Carter is sentenced to lifelong imprisonment in the frozen Ice Cells, while Savannah marries Felix, finally escaping her tragic past and finding true happiness.
