To save her mother and sister, who were about to be sold to drug traffickers by her gambling-addicted father, Sarah, a burnt-out corporate workhorse, binds herself to a romance conquest system. She accepts a mission that pays $100 million for each successfully conquered target, and simultaneously locks in three men: Sebastian, the king of the Dark Web; Alexander, the prodigy surgeon; and Dominic, the mafia lawyer.
For five years, Sarah devotes everything to them, yet their affection scores stay stuck at 30% due to endless framing and sabotage by their respective first loves. Desperate and disillusioned, Sarah finds that near-death experiences are the only trigger for their affection. She performs a string of suicidal acts—jumping into a frozen lake, falling from a skyscraper, and slitting her throat—which finally make the three men realize their mistakes.
In the end, the three meet at the hospital and discover they are biological half-brothers. When they lay down all their dignity to beg for forgiveness, Sarah demands to have all three of them. The moment their affection scores hit 100%, Sarah vanishes with her $300 million reward, leaving the three billionaire brothers drowning in everlasting regret.
