When Inji takes a job at Wedding & Life, the popular matchmaking service, she never imagines her role will be with NM, their secretive marriage division that rents out 'field husbands and wives' to their wealthiest clientele for a limited time. Just like a real marriage, Inji's assignments involve a wedding, some sex and a bit of housework, there is even a special helpline in case of any DV. It's all tailored exactly to the client's desires - no legal battles, no fights, no emotional baggage. In no way is Inji interested in finding real love, despite everyone trying to convince her otherwise - her brazen neighbour Granny, her flirtatious best friend Shi-jeong, and her failed blind date, Tae-seong. Then one of Inji's old husbands, a mysterious high-profile music producer, requests her back for another year. Soon Inji's own dark past will begin to unravel.
