An ordinary urban white-collar heroine who was forced to get married was forced to a desperate situation. In order to deal with her family, she posted a "rent a boyfriend" advertisement online. By some mistake, the rented "extra" turned out to be the ruthless new CEO of her company who was about to abolish her department. The two started a ridiculous cohabitation life in a trial marriage contract of "each takes what he needs", and staged a double life of "making a living under the CEO" and "showing affection in front of the parents".
