Choi Kang Soo is a deliveryman. In spite of his humble beginnings, Choi Kang Soo is fearless and gives it all in everything he does. Lee Dan Ah is another delivery worker. She hates her current socioeconomic status so much that she, like many young people, calls her country “Hell Joseon.” Lee Dan Ah is so focused on making money and changing her life that she has no time for men. But when she comes across the charming Choi Kang Soo, her attitude is due to be moved.

​

Together, Choi Kang Soo and Lee Dan Ah have a budding competition and romance in their quest for glory. And, for them, glory means being like rich folk Lee Jin Yoon and Oh Jin Gyu. They compete to conquer life but, as our two delivery workers soon learn, being the strongest does not guarantee success.
