Jung Kahi: An average albeit sarcastic and realistic girl. “Doesn’t take anything from anyone” kind of attitude.

Kim Jong In: K-Pop star known as Kai in rising to fame group “Exo-K”. Real life attitude as of now still unknown.

Inconvenience strikes when Kahi and Kai crash into each other on the busy streets of Seoul. After a quick switch of personal items, a problem arises. Unfortunately, they cannot meet up to simply exchange items – Kai is off on a world tour and Kahi is stuck in Seoul.

Now they have to cooperate and work together to figure things out. The problem? Kai and Kahi cannot possibly stand each other without knowing each other very well – will they get past these initial troubles and learn from each other or will this agreement end in utter disaster?
