Maomao tries to settle into her promotion to lady-in-waiting and food taster, but struggles to fend off both boredom and the overly-familiar Jinshi. That is, until she gets an assignment of her dreams: to concoct an aphrodisiac.

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.

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.

Lakan challenges Jinshi to produce blue roses to present at the upcoming garden party, forcing Jinshi to turn once again to Maomao for her help.

A concubine passes away, and a woman goes missing. Jinshi sends Maomao to investigate - not these incidents, but mushrooms growing in the rear palace.

Maomao's reputation for resolving conflicts reaches the empress dowager, who will ask for her help to unravel a mystery that won't leave her mind.
