Bottom-rung paparazzo Qin Chuan accidentally encounters female star Su Chuchu's wedding, witnesses her being dumped on the spot by her fiancé, and unexpectedly activates the Perfect Life System. For generous rewards, he temporarily steps in as the groom, and the two get their marriage license to start a contract marriage. Relying on the system, Qin Chuan acquires wealth, music, and other skills, purchases luxury mansions and cars, acquires Su Chuchu's brokerage agency, and supports his sister in forming a band. The two hand in hand deal with ex-entanglements and industry suppression, frequently produce ambiguous interactions, successively visit both sets of parents, and a falsely bound marriage slowly breeds genuine affection.
