The lives of Seok Ji Won (Ju Ji Hoon) and Yun Ji Won (Jung Yu Mi) have always been connected: their families, feuding for generations, both had children on the same day and named them both "Ji Won." Growing up, they appeared to defy their family history by falling in love in high school, but the relationship ended badly when Seok Ji Won moved away from their hometown. Now, as adults in their 30s, they've unexpectedly reunited at their alma mater – Seok Ji Won is the high school's new chairman, while Yun Ji Won works as a P.E. teacher. Their reunion brings anger, resentment, and buried emotions back to the surface, and the two are forced to confront both each other and their unresolved past. Can they manage to find love again, or is their relationship best left in the dust?
