Ji Hyun and Lu Han are childhood friends, who used to spend every day playing with each other and even made a promise to never separate. But what happens when Ji Hyun's parents decide to move from Seoul, South Korea? What will happen if she returns years later? Is the friendship still there or was it eliminated the day she left?

Before anything else, do not plagiarize please. If anyone did, please inform me. While you were young, Luhan's parents are close friends with your parents. Then, they have decided to arrange your marriage. Time passes by, you're now a teenager, and they kept it as a secret. Meanwhile, you're enemies with Luhan. Will you be still enemies? Or would the two of you make up?
