Lisa is a graceful young woman from the Astralis Kingdom, a medieval-style realm in a parallel world. After a portal spell malfunctioned, she found herself stranded in Gangneung, South Korea. Hiding her royal background, she now lives in a small rented room above a café, working part-time to blend in while searching for clues to return home. Though she is polite and refined, she struggles with the quirks of modern life and Korean culture. As days pass, she grows attached to her new surroundings — and to a certain someone.
