"I bet you'd never think that the sweetest guy on earth is cheating on his first ever girlfriend, would you? No. You wouldn't. Well, you wouldn't think that he was if you knew who that "sweet guy" was. Kevin Woo. My first boyfriend. And I'm his first girlfriend...well...I was."
Wong Haneul is twenty years old, a model, a singer, and three years younger than her first ever boyfriend. Haneul debuted a year ago with her best friend, Nari. They both form the famous K-pop duo, Trouble. They're known internationally as the Queens of K-pop, because of their many different styles. They can do y, they can cute. They can do rebellious, they can do funny. No matter what they do, to their fans, Troublemakers, and U-Kiss's fans, Kiss Me(s), the two girls rule. Haneul is the main rapper and main dancer/choreographer, and Nari is main singer, and songwriter. They're both equal, so neither are the leaders, but it's clear Haneul is more active with the fans and variety shows. When Haneul meets Kevin Woo, her life turns upside down. They train together, they sing together, they even travel together. As they're under the same company, NH Media, they see each other practically all the time, and tend to share concerts with each others groups when on tour. Kevin made the first move to ask Haneul out.
