In the heart of Seoul lies a mysterious, centuries-old hotel catering exclusively to ghosts. It’s run by Jang Man Wol, a resentful and greedy woman who’s been bound to the hotel for a thousand years as punishment for her past sins. Cursed by a deity, she can only break free by letting go of her hatred and learning to love again.

Enter Goo Chan Sung, a former hotel assistant manager forced into working at the ghostly hotel due to a deal made by his late father. As he takes over the hotel's operations and manages its unusual guests, he may just hold the key to Man Wol’s long-awaited redemption.
