To fend off her family’s relentless pressure to marry, an ordinary office worker in the city posts an ad online to “rent a boyfriend.” By a twist of fate, the “temporary actor” she hires turns out to be the ruthless new CEO of her company, who is about to shut down her department. Their trial-marriage contract, in which each gets what they need, launches them into a hilarious life under one roof. Together, they lead a double life: trying to survive under the CEO at work while putting on a loving display in front of their parents.
