She Was Pretty

Hye-jin, who was the prettiest girl in school, has changed drastically since then. After seeing her old friend and first love Sung-joon again, Hye-jin asks Ha-ri to pretend to be her.

Hye-jin has to see Sung-joon at work everyday when he joins her team as an editor. Sung-joon still believes Ha-ri is Hye-jin and treats the real Hye-jin harshly.

Shin-hyuk notices something strange between Hye-jin and Sung-joon. Hye-jin tries her best and learns about fashion to impress Sung-joon.

Shin Hyuk tells Hye Jin to treat him like an older brother, and Hye Jin ends up calling Sung Joon under the influence of alcohol and reveals that she is his first love.

As Ha-ri begins to fall in love with Sung-joon, who thinks of her as Hye-jin, she asks Shin-hyuk to pretend to be her fiance.

Sung-joon gets sick and Hye-jin worries about his condition. While spending time with Ha-ri, Sung-joon realises she is different from the Hye-jin he used to know.
