Kkondae Intern

A condescending ex-manager starts over as an intern at a new company, where an employee he tormented turns out to be his new boss.

After five years, Yeol Chan successfully becomes a general manager at Joonsu Food, Ongol's rival company. On the contrary, Man Sic is on the verge of getting laid off from Ongol due to his age. Man Sic even declines the warehouse management position that the company is offering. In the end, Man Sic joins Joonsu Food with an unusual job position and meets Yeol Chan for the first time in five years.

Sang Jong tries his best to get Man Sic to join Joonsu Food as a senior intern. After sleeping on it, Man Sic starts his first day in the office. However, he recognizes a familiar face: Yeol Chan.

A war starts. Yeol Chan promises to repay all the hardships Man Sic put him through. Man Sic, on the other hand, pledges to stick with it until he puts his son through college. Not only that, his friend Ahn Song Jong at Joonsu Food puts him on a secret mission.
