After the cannon fodder heroine Song Cixing awakened, she gave up escaping her fate and instead regarded marriage as a "high-risk career". She took the initiative to negotiate a marriage with Su Mingyuan, the richest man who was rumored to be cruel and perverted. The two started with an employment relationship, earning a daily salary of 100,000, and lived together in a trial marriage. In the tug-of-war between money and temptation, Song Cixing, who appeared to be sober and rational, was gradually moved by Su Mingyuan's awkward guardianship and paranoid domination; while Su Mingyuan, who was regarded as cold-blooded by the outside world, also found the only softness in her. When a two-way secret love turns into a two-way "perverted" possession, a high-risk cooperation that begins with interests eventually evolves into the ultimate redemption and grand wedding for a crazy couple.
