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.

An older acquaintance of Jinshi's dies while drinking at a party. A servant's body turns up in a moat. Both deaths are written off as self-inflicted, but Maomao's keen observations tell her that there's more to both stories.

A tea party hosted by Lady Gyokuyou puts the politics of the rear palace at the forefront, and Maomao learns something new about Lady Lishu. His true intentions unclear, Jinshi sends Maomao to work for Lady Ah-Duo.

Maomao confronts Fengming about the dark secret she's been hiding from her noble Lady Ah-Duo.

Discovering that Maomao's kidnappers were connected to Fengming's family, Jinshi is faced with a choice between keeping Maomao in the rear palace where he can be near her or releasing her from her service.

To Maomao's surprise, Jinshi brings her directly to his house instead of taking her back to the rear palace, and tells her she's to work in the outer court. Not only is there much to learn, it seems there's many eyes on her as the new hire.

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.

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.

No longer willing to keep running away from Lakan, Maomao decides to face off against him. She challenges him on his own turf, in a chess match.

Lakan must now choose a courtesan to buy out. As a high-ranking military official, he can afford to freely choose, even from one of the Three Princesses. Who will he choose? Who does Maomao really want him to choose?

The spring garden party concludes without incident. Maomao returns to her regular life as Concubine Gyokuyou’s taster. Meanwhile, novels become popular in the rear palace.
