You (Xi Lu Wen) are Luhan's younger sister. You are 1 year younger than him but you two have a striking resemblance that people thought you were twins and sometimes people mistaken you for Luhan or vice versa. Your brother had been appointed as the Page for the newly crown Prince Chanyeol in Korea but he had to go abroad for further studies in order to take up your late father's job and inherit his property and he doesn't want to disapoint the Prince so he asked you to pretend to be him and take his job while he was away. Will you be able to keep your hang on and keep this secret??
