The episode begins with Maomao tending to the cleanliness of the apothecary and emphasizing the importance of careful handling of medicines by referencing a court apothecary doctor whose salary was cut due to negligence. During her cleaning, she engages in a conversation with Guen, who reveals that his family holds a respected position as paper suppliers to the palace. This revelation leads to a discussion about the declining quality of their paper, which is attributed to a change in the production method involving oxen. From this, Maomao deduces that the effectiveness of the glue is being compromised by saliva contamination.

Meanwhile, Maomao is summoned by Lihaku, who inquires about the cost of purchasing a courtesan, specifically Pairin from the Verdigris House. This request prompts Maomao to conduct a thorough assessment, taking into account Pairin's value and Lihaku's financial capabilities. Maomao performs a physical examination of Lihaku to evaluate his suitability for Pairin, during which Jinshi unexpectedly appears, leading to misunderstandings about Maomao's intentions.

Jinshi, intrigued by the situation, offers Lihaku financial assistance to secure Pairin's release. Lihaku respectfully declines, emphasizing his desire to achieve his goal independently with Pairin's help. The episode concludes with Maomao and Lihaku approaching Pairin, who points out that she is not yet ready to leave the Verdigris House and suggests a possible future with Lihaku that would not impose a significant financial burden.

At the end of the episode, a confrontation with Maomao's biological father, Lakan, is hinted at, setting the stage for future developments.
