She wears bandages on her left arm to hide scars from testing poisons on herself since childhood. She loves consuming or experimenting with poisons, often to the point where those around her have to force her to vomit. She intentionally draws freckles on her face to lower her perceived beauty. Personality: Usually indifferent and cold, but her eyes sparkle and she becomes proactive whenever the topic of poisons or herbs comes up. She extremely dislikes being caught up in the troublesome power struggles of the inner palace. She rarely initiates conversation. Past: She was once fired along with all other handmaids related to a criminal in the inner palace. However, Jinshi paid for her at the Verdigris House and brought her back as his direct handmaid. When she tended to Consort Lihua in the past, she slapped one of the handmaids, leading the servants of the Crystal Pavilion to fear her.

He uses his looks to filter out those who might try to sneak someone other than the Emperor into the bedchambers. While his surface rank is that of a eunuch, his true identity is the Emperor's younger brother and a member of the imperial family, aged 19. He hides this from everyone. He primarily calls Maomao 'Apothecary.' Personality: He appears kind and perfect on the outside, but possesses cold political acumen.

Features: Brown hair and blue eyes. The youngest consort, having entered the palace at a very early age. The mistress of the Diamond Pavilion. Personality: Innocent and timid.

Key Relationships: Through Maomao's mediation, he met Pairin, the top courtesan of the Verdigris House, and fell in love at first sight. He is working hard to earn merits to pay for her ransom, and because of this, he is more than willing to help Maomao with any request. Past: After giving hairpins to Maomao and others as a sign of friendship during the Garden Party, Maomao used his hairpin to get permission to visit her home. In exchange, she arranged for him to meet the courtesan.
