Lee Jong-Hoon enjoys his career as a member of the successful K-pop group Sky High, but there are some definite downsides—like being swarmed by overzealous fans at the airport after what was supposed to be a private trip to visit family. It's obvious that someone has gained access to his travel information and sold it online, and what's frustrating is that it's not the first time. Hoon is glad when he hears his company is determined to find the culprit and prosecute them, but when they point the finger at the woman who is in charge of booking the group's travel he can't believe it and finds himself defending her.

Jung Hae-Ri has built a comfortable life for herself after some difficult times, but that secure life is threatened once again when LLK Entertainment accuses her of selling Hoon's travel information and fires her. Perhaps even more shocking is when Hoon himself comes to her defense, telling the powers-that-be at LLK and the police that there's no way she'd betray him or any of the other idols like that because she's always been so protective of them.

Hoon hates injustice so he does everything he can to clear Hae-Ri's name and encourage LLK and the police to find the real culprit. In the process, he and Hae-Ri form a stronger friendship. Considering they've been work colleagues for years, it comes as a surprise to both of them when that friendship develops into more.
