Hwang Tiffany is a typical teenage girl with a bright and bubbly personality but loses her temper easily and can be a bit arrogant something. “She is just like a baby, her mood changes in a snap” says her close friend Jessica Jung and Kim Taeyeon. Her relationship lasts no longer then a month, and most of the time ending up with just a painful crush. “Unlucky in love” she tells to herself. Secretly believes in “soul mate” and “forever and after”. Since her relationship never works for her, she forces herself to think that such thing doesn’t exist. But all the changes when she accidently meets Lee Joon, who is popular for his good looks and his strong dancing skill. Even thought he looks cold outside, once he opens up his heart he is completely opposite. He is funny, caring and romantic. 

Can Joon become everything Tiffany has ever wanted? Will she be able to resist Joon’s charm? Can Joon break Tiffany’s theory that she believes in “Unlucky in love” proving her that “soul mates” do exists and so does “forever and after”. Are they meant to be or is this just a pure coincidence? A fate maybe?!!!!!
