Sinbi Apartment: Joseontoemasillog

Hari, Duri, and their friends expect little more than a fun encounter with the world of a historical drama, until Geumbi's magic sends them roughly 500 years into the Joseon era. The group is scattered around Gyeongbokgung Palace, and Hari is mistaken for Princess Hyowon because of their striking resemblance.

The palace is already being haunted by dangerous spirits, while someone in the shadows is using supernatural forces for a larger purpose. Separated from the Geumbi they know and stranded in an unfamiliar age, Hari, Kanglim, and the others must uncover what is happening inside the royal court, protect the people caught in the haunting, and find a way back to their own time.
