Maomao does her best to navigate the complex social situations at the garden party, including meeting the other Upper First rank concubines. But once she settles down to do her work as a food-taster, she discovers a surprise in a bowl of soup.

Gaoshun goes to Maomao to get her help in resolving the events of the garden party. Later, Xiaolan explains the purpose of the hairpins Maomao was gifted, and Maomao makes a deal with Lihaku in order to finally visit home.

Maomao's peaceful morning at home is interrupted when she's called in to investigate an apparent double suicide at one of the local brothels.

Ah-Duo's replacement has arrived in the rear palace, and Maomao is assigned to give a certain lecture to all four high concubines. Later, Maomao helps Lihaku investigate a warehouse explosion.

A discussion with Lihaku about recent events leads Maomao to realize that the mysteries she's helped to solve are connected. As the final piece of the puzzle falls into place, she rushes to stop impending disaster.

Maomao was able to stop the assassination attempt, but was heavily injured in the process. However, the injuries aren't enough to stop her curiosity, driving her to confront the culprit behind the incident.

Back to work at the rear palace, Maomao listens to Guen talk about his family's business. Meanwhile, Lihaku hears a rumor that whips him into action.
