50 Days of Some

A chaotic, time-limited office romance centers on Go Dok-hee, an invisible and historically unlucky retail intern who unexpectedly acquires a magical potion that makes anyone fall desperately in love with her for exactly 50 days. Her ordinary life turns upside down as she navigates an expiration-dated romance with her office colleagues, including the sharp-tongued assistant manager Choi Geon-guk.
