Jin-mi, a manager at Seorin F&B, a food service company, plans to go on a trip with her mother to celebrate her mother’s 60th birthday. But several days before the trip, her mother dies in a car accident. Jin-mi regrets not traveling with her mother even once
before she passed away. Full of self-reproach, Jin-mi rushes to the airport carrying an urn filled with her mother’s ashes in her black mourning clothes. She takes the first flight she can get and arrives in New York City. Utterly bereft, she blankly looks at the dark water as she stands on the Brooklyn Bridge. Someone approaches her and puts a coat around her shoulders. It’s a man who has a welcoming smile and a friendly voice. He treats her like a long-lost friend. He takes her to a hotel, treats her to a delicious meal, and gives her
a silver-dollar coin, a symbol of luck. However, he disappears even before she asks his name. Will she ever meet the man again?

Perhaps because of the meal that the man had offered, Jin-mi safely returns to her ordinary life. Eight months have passed and she successfully made a franchise contract with Delicacy, a famous restaurant based in New York City. She arrives at Incheon Airport
after a business trip where she encounters the man she met on the Brooklyn Bridge again. However, the man has a hopeless look in his eyes and jumps in front of a car as if attempting suicide. As he comes to his senses, the man naively asks Jin-mi, “Who am
I?” He tells her that he’s been deported from the United States without knowing why. The only thing he remembers about himself is his own name, Young Yun-je, written on his temporary passport. Although she has longed for this reunion, Jin-mi still knows nothing
about the mysterious man.

Jin-mi has no choice but to take him to her home. Unexpectedly, as he removes his cast, he excels in cleaning, fixing, and everything
else. And he cooks remarkably tasty food by only following recipes from a cookbook! He even plays various roles: housemaid for Jinmi’s best friend, babysitter for the kid next door, and fill-in for a neighborhood grocery store employee. But what is the most crucial role for Yun-je? For quite a long time, there’s been a rumor that Jin-mi is the secret mistress of Kim Seok, the director of headquarters of Seorin F&B. Gu Sang-kyung, the fiancée of Kim Seok and heiress of a conglomerate, is suspicious of their relationship and makes Jin-mi get demoted. Jin-mi challenges this and shows up with Yunje as her boyfriend. From that day on, Jin-mi and Yun-je’s fake relationship begins. However, as time goes by, they are confused about the nature of their relationship. Are they really fake lovers?
