Kim hye Jin is a high school student who is in love with Wu Yi Fan also know as Kris, an ulzzang rich boy and part of exo m member. Apart of being a fan girl, hye Jin is also their friend. One of the member is her best friend, Luhan who she  grew up with. It's almost like they where real siblings because of how they treat each other, sometimes they're sweet and sometimes they would fight. Ever since Luhan and  hye Jin entered high school, Luhan became a member of exo m. Kris who is the leader discovered the potential that Luhan has. He has the face, the talent and the whole character of an "Idol".

At first Luhan didn't like the idea of being in their group because he thought it was very bothersome and most of all it would just cause problem to his studies but when hye Jin saw kris being also in that group, she pleaded and persuaded him to enter that group. With so much pleasing, Luhan couldn't stand it anymore, so he agree to it.......... BUT!  In one condition, Kim hye Jin have to give 3 wishing coupon. Every time he wants her to do something for her,  hye Jin must have to do it. Immidiately Jin agreed to it without saying any other word after that.

Luhan almost drop his jaw in disbelief, because he knows that Jin is not the person who would accept those kind of deals, but he just shook her hand anyways still dumbfounded.
