This sitcom follows two longtime rivals who now work at Ruammit Radio. Kaembum, freshly graduated from abroad, returns to manage her family’s company. Nine, the station's general manager, is the powerhouse behind its programming.

But their rivalry runs deeper—they were high school classmates. Nine was the charming athlete at the back of the class, while Kaem was the studious girl with braces and freckles at the front. Their battles to outwit and embarrass each other started early and never stopped.

Now reunited as colleagues, their clashes light up the office—and things get even messier when Kaem moves into the condo right across the hall from Nine.
