Im Jinah, known to the fashion world as "Nana," was a top class fashion designer. She was an astringent, fearless, and seemingly emotionless Chief Executive of the presitigous label "I.M Attire." Designing everything from dog to fashionable old woman clothes, the company was well known. Although seemingly emotionless, it is revealed she has a problem with rain and anything having to do with it. 

Park Sooyoung, known to the world as Sooyoung, was her assistant. She was a normal young woman that just needed a job. She likes not to test boundaries and stay within the lines, but when she learns about her boss' complication with rain, she made it her new job to figure out why. No matter what it takes.
