Yoon Dan Oh had enjoyed a comfortable life as the beloved youngest daughter of a well-off family, but not anymore. She is now the breadwinner of her family and runs Ihwawon Inn, where many of the guests are scholars who came to Hanyang to take the civil servant entrance exam for becoming ranking officials.
Among the scholars staying at Ihwawon Inn are Kang San, Kim Si Yeol, and Jeong Yoo Ha, all of whom have deep secrets. Yoon Dan Oh and the boarders combine their information and work together to find Lee Seol who disappeared 13 years ago.
