30-irui Yakonnyeo

A South Korean woman working in a research lab receives a text message just before being struck by a truck, offering her a journey, new relationships, and financial opportunities. She accepts and is transported to the Raotwan Empire of Laseania, where she becomes the 12th fiancée candidate, Isella Derhen, under Duke Adrian. She must maintain the role for a month to return to Earth, deceiving nobles, the empire, and the emperor. Duke Adrian, patriarch of House Beleskez, seeks a fiancée to avoid a royal marriage with Princess Kiersten, the emperor’s daughter. He cannot refuse the marriage due to political tensions, so he looks for someone to impersonate his fiancée until his son, Lord Aslan, can assume the dukedom. Inseo must avoid falling in love with Adrian as they attempt to pull off the deception.
