Jaehwa made a promise to her friend Jiyong that they will become the most succesful rappers in Korea, but before starting middle school, her family were going to move to Australia, and with a short goodbye and no explinations she left. 

8 years later, her parents send her back to Korea for getting into too much trouble. She stays with her friend she met in college, but she can't seem to forget her promise to her friend she made those years ago. So when she sets out to find Jiyong, she gets more than she bargained for.

The Jiyong she knew isn't the Jiyong she remembered, and his new attitude and strange behaviors isn't something she can comply with. 

Will she bring out the old Jiyong again?
