Hye Jin was once rich and pretty, but now she has freckles and frizzy hair and is struggling to stay employed. Shy and portly as a child, Ji Sung Joon has turned into a tall and handsome professional after growing up abroad. Feeling insecure about her appearances, Hye Jin sends her glamorous best friend Min Ha Ri (Go Joon Hee) to see Sung Joon in her stead, figuring that one meeting would be the end of it. However, Sung Joon turns out to be Hye Jin’s new boss at work, and the two immediately start off on the wrong foot. Meanwhile, Ha Ri continues to pose as Hye Jin as she gradually falls for Sung Joon.
