Yang Mi Sook has spent her entire life being unrecognized due to her scruffy hair, flushed face, and awkward demeanor. She is known as Miss Carrot and teaches Russian to high school kids who don't pay attention while wistfully yearning for her coworker Seo, who she has had a crush on for ten years. Mi Sook, who is content with her mundane, delusional life, is propelled into action when hot young instructor Yuri enters the room and snatches both her class and her boyfriend. Mi Sook establishes an odd partnership with Seo's misfit teenage daughter, who is just as crazy as she is, to put an end to their blossoming affair.
