When Noh Inji first accepted a job at Wedding & Life, the popular matchmaking service that’s taken Korea by a storm, she never imagined her role would be with NM, their secret marriage division that rents out “husbands” and “wives” to their wealthiest clientele. Just like a real marriage, Inji's assignments involve a wedding, some sex and a bit of housework, all tailored exactly to the client’s desires and length of time before they go their separate ways – no legal battles, no fights, no emotional baggage. After several marriages, Inji has become an old hand. She certainly isn’t interested in finding real love, despite everyone trying to convince her otherwise. Then one of Inji's old husbands, a mysterious high profile music producer, requests her back for another year. Over the course of their marriage, the secrets of Inji’s past begin to unravel – as well as the dark, sinister underbelly of the NM’s management team.
