The Hotel del Luna is situated in the centre of Seoul and has a very old-fashioned appearance; however, it has a charming interior that only its ghostly guests can enjoy; consequently, there are ghosts wandering through the halls. Jang Man Wol is the hotel’s CEO, but due to a mistake made many years ago, she has been living under a curse for over 1,000 years and has been confined to the Hotel del Luna. She is beautiful and elegant, but she is not kind to others. She is also fickle, suspicious and greedy. Goo Chan Sung is the youngest assistant manager at a multinational corporation and is a perfectionist. He appears composed, but in reality has a tender heart. Following an unexpected coincidence, he begins working as a manager at the Hotel del Luna.
