Choi Dae-hyun (Ji Chang-wook) is a young convenience store manager. He is very gentle and a little off-line, and he is deeply trusted by his subordinates. Choi Dae-hyun loves his job very much, but he must face a choice, that is, whether to continue to do this job in the convenience store that is not competitive and has no future, or to enter a large enterprise and embark on the peak of life that people recognize in the secular sense. Liu Yanzhu (Han Sun-hwa) is Choi Dae-hyun's girlfriend, an excellent woman with both beauty and wisdom. Liu Yanzhu has received an elite education since she was a child. His family naturally hopes that their daughter can find a husband who is on par with her, rather than a "convenience store part-time worker." Choi Dae-hyun's career has become an irreconcilable obstacle to their relationship.
