It all begins when the sister of the lead character gets married and, ashamed of her, sends her on vacation to Jeju Island. There, she meets a handsome man with whom she falls in love, but suddenly leaves him to return home to her mother, who is hospitalized for illness caused by the married daughter's debts.
Burdened by debts (house and hospital) she applies for a permanent job but among the jury there is him, disappointed at having been rudely dumped, who refuses to hire her.
But he finds himself being her boss in this department specifically created by his sister to put him in difficulty. The team works hard and he will protect them even when it emerges that his employee isn't married and falsified her CV to get hired.
The problem is that she's been passing herself off as "married," and he becomes jealous. So, he decides to rush things by marrying the girlfriend chosen by the family. Then he discovers that his employee isn't actually married (but did it to get hired) and that her girlfriend is also in love with her "husband."
They get secretly engaged. After overcoming his brothers and putting his mother back in charge of the company, he gets hit by a car and loses his memory. He leaves her, and a year later they meet again on Jeju Island and start their relationship over again. The situation after a few years: they're married with two children, and the couple they've known are still just friends (too bad).
