Behind SM Entertainment’s success, there is one special girl that stands just like the others. Tiffany Hwang was born in the United States but an unseen tragedy paved a way for her to finally settle in South Korea. Even without her original family beside her, she has grown up well because of the Hwang family’s butler, Robert, and his care for her.

One day, Tiffany attended EXO’s Overdose performance, watching as her works contribute to one of SM’s most popular dance groups. Lee Soo Man comes over to her, congratulating her on a job well done before inviting her to meet SNSD in person. Of course, she hadn’t had the time to actually meet other SM artists because she was busy composing songs for them so she agreed.

Upon meeting them, she thought it would be nice to have a family like the girls had. The members feel the same way, making time to meet with her as a group, sometimes as individuals. As she gets more and more involved with them, she slowly uncovers secrets she never knew existed in the real world. They were involved, and now, she was also involved.

But when the person behind it all, know nothing of the consequences of his actions, who is to blame? The person who knew but didn’t have any control? Or the person behind it but didn’t know a thing?
