Kim Soohye is a normal high school student. She has a group of friends, loving parents, and an annoying brother.  But what if she's given a chance to be an exchange student in Seoul's prestigious high school? Will she accept the offer and leave her family and friends behind? Will she take the risk of going to an environment she's not used to?

Lee Jinki is rich, smart, handsome. In other words, perfect. But guess what?! He's not a kingka or the school's bully or even a playboy? You know why? He can't stand to stay in a group of friends. Maybe more like, he can't stand to have even one friend. Why? No one knows. Everyone wants to be his friend. Who wouldn't want to be-friend Seoul International High School's (just pretend this school exists. Neh? :D) richest student. He received offers from different group of kingkas. The music club asked him to join them. Every club in the school asked him to join them! But he rejected all of them! He did not say a single word, but just smiled at them. A smile that would cause girls to die of excessive blood loss because of too much nose bleed. He looks very friendly, but at the same time, mysterious.
