Daehyun, as girl, bumps into Youngjae. And Youngjae thinks Daehyun is the ugliest girl he's seen in his life, however, Himchan, who's the stylist, says Daehyun could be the prettiest girl ever with proper clothes and make up and Youngjae should hire her for the next magazine's cover. And it’s how misunderstandings start between Youngjae and Daehyun as Youngjae falls in love with Dasom slowly (Daehyun’s girl's name) and Daehyun falls in love back.
 

And to make things more problematic, Daehyun gets a job as photographer at the magazine and he has to take pics of Dasom.

Ps: I couldn’t stop thinking after Daehyun’s Halloween costume as Harley Quinn.
