Han Se-kyung is a person who tries her best in getting everything and lives by the motto of “Self-achievement generated from hard working”. Though she studies design, because of her family’s financial problem, she doesn’t have the opportunity to study design abroad. And for this reason, not having any abroad studying experiences, she is often rejected by job interviewers. After three years, surprisingly, she is offered a job as a temporary worker at a clothes designing company called GN Fashion. She doesn’t become a designer in the company; she becomes an errand girl for the head lady. When she is delivering some bags once, she bumps into Cha Seung-jo’s car.

He hides his identity as the president of Artemis and introduces himself as the secretary of the president of Artemis.

He decides to collaborate with GN Fashion, which is Seo Yoon-joo’s husband’s company. Seo Yoon-joo, aware of the collaboration, asks his husband, Shin Min-hyuk, if she can be in charge of setting up the dinner between Jan Thierry Cha and him. Shin Min-hyuk agrees.
