Joon-hwi seems like a regular office worker. But the truth is, he’s actually an undercover boss who is first in line to succeed the chairman. With his stylish and dashing good looks, many women show their interest in him. However, as a man who doesn’t believe in marriage, he rejects all of them. He is also a strict individualist who absolutely detests being on the giving or receiving end of loss. On the other hand, Cheong-ah is a bit pathetic, barely scraping by with part-time jobs while attempting to pass the civil service exams for the eighth year in a row. A real-life youthful romance begins when Cheong-ah, a girl who is loyal to a fault, meets Joon-hwi, a self-centered ‘man of the times’ who doesn’t believe in marriage.
