A group of friends abandoned their lives in America and nearly-spontaneously moved to Seoul one day to start off their new lives the winter after high school. One day, when working at the Cafe, EXO walks in, leaving the shocked girls with no choice but to serve and interact with them. 

Each of the girls has a unique personality and, when combined with the members of EXO, all hell breaks loose. 

Can they convince the boys to trust them and to keep coming back?

They all have their own story to share: love, friendship, and hard times are fast approaching the normal, unsuspecting girls.  

Mina

The loud, smart girl who always has several smart-alec comebacks at the ready, and is cold to people when she first meets them. She cares for her friends deeply and is known as the mother of the group because of her cooking and cleaning skills, despite the fact that she is the second youngest. She can be quite erted at times, to the dismay of Ana and Nina. She is from a country in southern Europe.

Nicole

The loud, mood-making maknae of the group who can be just as erted as Mina, and brings joy to the group. Without her, they wouldn't have the amount of fun they have now. She is the only person who can bring their spirits up when they are feeling down, and she is very proud of that.

Nina

The oldest and possibly the most normal out of the group. She brings control to everyone and is very intelligent. She's the sweetest person you could meet, and you can't help but feel happy when around her. She is considered the twin of Ana for their similarities in interests and personality.

Ana

The second oldest who is extremely quiet when around strangers, but gets very comfortable and breaks out of her shell when with her friends, at which point she becomes one of the loudest and most hyper people in their group. She loves to read, and is sensitive to the erted comments Nicole and Mina often make. She, too, is from a southern country in Europe, the same as Mina.
