In one of the famous nightclubs in the city, there's a well-known DJ, her name is Moonbyul. She has always been passionate about making music, she became one of the best female DJs in the area and was respected for what she does best. On the other hand, there's a girl named Solar. She always has been labeled as "goody two shoes", working as a Marketing Director, for a young age she needed to prove her worth a lot at work to be able to reach where she is now.  Work, home is the only thing she does. How can possibly two polar opposite people cross paths?
