The Secret Romantic Guesthouse

While touting her residence service on the street, Dan Oh encounters a group of hooligans. Fortunately, a stranger emerges and rescues her from the predicament. Undeterred, Dan Oh continues her efforts and soon encounters a skilled swordsman whom she believes would be an ideal guest. Along with another guest from Garden of Flowers, the four individuals become involved in an unexpected and dangerous situation.

Dan Oh becomes aware of her grave predicament upon discovering that some individuals are plotting to seize control of Garden of Flowers. While dealing with a bothersome man on the street who offers to settle her debt if she marries him, Dan Oh vehemently refuses his proposal. As she gains further insight into the financial burden left behind by her father, Dan Oh devises a plan to settle the debt without realizing the unintended consequences that could arise as a result.

Garden of Flowers is the most significant thing for Dan Oh, and she is determined to do everything in her power to keep it from being taken away. Dan Oh informs everyone that she has business in Gwacheon-hyeon and will be away for a few days. Although the three young masters initially feign indifference, they end up following her. Dan Oh keeps her search for Lee Seol a secret, oblivious to the risks that lie ahead if she persists.

Despite the danger that it may pose, Dan Oh continues her search for Lee Seol. Meanwhile, the young masters also end up supporting her search, but not everyone is pleased with her endeavour. Her hard-earned clues lead her closer to Lee Seol, and the danger she faces grows as she gets closer. However, the closer she gets, the greater the peril she encounters. Upon returning to the inn after attending to personal matters, Kang San unexpectedly collapses upon encountering Dan Oh.

Dan Oh finds Kang San collapsed in the street, and brings him back to Garden of Flowers, but his condition appears critical. However, thanks to Si Yeol's unexpected yet exceptional medical skills, San is able to survive the poisoning. Meanwhile, Dan Oh hurriedly looks for Si Yeol when she hears the news of his arrest. All her efforts to protect Garden of Flowers seem meaningless, but her care for the young masters continues.
