As the beloved youngest daughter of a well-to-do family, Yoon Dan Oh (Shin Ye Eun) lived a charmed life. At least she did until the day fate dealt her with a rather cruel blow. No longer able to indulge in the carefree lifestyle of a cherished daughter, Dan Oh must do everything she can to help support her family.

The proprietors of Ihwawon Inn, Dan Oh, and her family warmly welcome those looking for a place to stay during their visit to Hanyang. As the majority of those traveling to the area are young men preparing to take the civil servant entrance exam necessary for becoming a ranking official, Ihwawon Inn is frequently visited by a large number of scholars. Among those scholars are Kang San (Ryeoun), Kim Si Yeol (Kang Hoon), and Jeong Yoo Ha (Jung Gun Joo), three very different young men who each harbor a deep secret.

While the young scholars prepare for the exam they, along with Dan Oh, stumble upon bits of information that all seem to tie into a strange disappearance that happened thirteen years ago. Pooling their knowledge, will this unlikely quartet be able to solve this mystery or will they find themselves too distracted by the sudden and unexpected flutterings of their unruly hearts?
