Jung Eunji & Park Chorong are Two Best Friends.
Because of their parents... Loan sharks are chasing them, they are really poor, and have multiple jobs that they can't keep. 

Because of their free willed fighting spirit and their spirit to never give in to people, they always get fired from jobs.

One day, they were doing a job that requires them to sing for fun. After that, a scouting agent told them to sign a contract with him. 

But.. They somehow get scammed and life gets worse or better, what will happen? And what did happen?
