Yang Mi-sook is an unpopular and frumpy high school russian teacher, who has a habit of going red in the face. For ten years she has been harbouring a crush on Seo Jong-cheol, her former teacher and now married colleague, though he is more interested in pretty new teacher Lee Yoo-ri. Mi-sook tries to put a halt to this blossoming romance, forming an unlikely alliance with Jong-cheol's daughter, Jong-hee.
