What will happen if you combine a Badgirl and a Dancer? After a heartbreak, Cathy Song turned opposite of what she was before. From good girl to bad girl. She believes that no one can help and answer her problems rather than go clubbing and break relationships. Until Kim Jong In or Kai, a member of the famous EXO, claimed Cathy as his girlfriend in front of many people. "Who the heck are you?" Cathy asked. "Shut up. I'll just dance half-naked in front of you later as a payment."
