Chanyeol is a professional chef who owes an italian restaurant in the central district of Seoul. He's handsome and rich and he rarely encounters a series of unfortunate events, that is until he met King Wang Eun( birthname: Baekhyun) who mysteriously appeared from the 18th century together with his bodyguard, Do Kyungsoo and royal secretary, Kim Minseok.

He decided to confess his love for Jihyun but he has another competitor Kim Seonho, a basketball player and classmate who has a crush on Jihyun too. Will Kyungsoo be able to win Jihyun's heart?
