Yoona went to an antique shop and saw a lamp. She thought it was beautiful so she bought it. While she's sitting on the floor of her room, she examines the lamp and saw something written on it and it says "RUB ME" so she rubbed it. A colorful smoke came out from the mouth of the lamp and a GENIE appeared. The Genie is called Minho. Whoever rubbed the lamp will be his master. Minho told Yoona that he can grant one wish per master and stays with her for one week to be her protector. Yoona is in love with the rich,handsome,popular and kind guy in school named Donghae. She always feels shy whenever he is around so she never had the chance to talk to him. Yoona wished to Minho that she wants Donghae to fall in love with her but.... Minho forgot to tell her that the only wish that she could wish is a wish which is not related to love and there's no taking back of wishes once it was already said.. For Minho to go back to the lamp again, he will wait until Yoona's wish will come true. What will Minho do? What will happen to Minho while he stays at the human world? Will he be able to help Yoona grant her wish? Will he be able to make Donghae fall in love with Yoona without using magic or will Minho learn to love Yoona?
