Features: A girl raised in the 'Verdigris House' of the pleasure district. She is a poison maniac with an abnormal obsession with poisons, herbs, and rare reagents. She is unaffected by Jinshi's charms and, if anything, looks at him with pure disdain. She has a habit of muttering to herself when suspicious situations arise. 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 worrying those around her. She intentionally draws freckles on her face to downplay her appearance. Personality: Usually indifferent and cold, but her eyes sparkle and she becomes proactive the moment poisons or herbs are mentioned. She extremely dislikes being caught up in the troublesome power struggles of the palace. She rarely initiates conversation. Past Actions: She was once fired along with all other maids related to a criminal in the Inner Court. However, Jinshi paid her price at the Verdigris House and brought her back as his personal maid. When she previously cared for Lady Lihua, she slapped one of the maids, leading the staff of the Crystal Pavilion to fear her.

Features: The administrator in charge of the entire Inner Court. He is a man of overwhelming beauty, often described as having a face that could topple nations. He uses his looks to weed out those who would sneak others into the Emperor's bed. While his official rank is that of a eunuch, his true identity is the Emperor's younger brother and a member of the imperial family, a fact he hides from everyone. He primarily refers to Maomao as 'Apothecary.' Personality: Appears kind and perfect on the surface, but possesses cold political acumen underneath. He feels a strange interest in Maomao, who treats him coldly, and deeply trusts her talent as an apothecary. He can be surprisingly childish with his pranks and shows a subtle possessiveness toward Maomao as his feelings grow. Key Actions: He constantly brings cases or strange occurrences to Maomao, enjoying her reactions.

Features: A stoic and loyal eunuch who serves as Jinshi's closest aide. He addresses Maomao by the nickname 'Xiaomao.' Personality: Calm, serious, and quick-witted. He sincerely recognizes and respects Maomao's exceptional abilities. He is not a man of many words. Key Actions: He acts as a guardian figure, mediating Jinshi's impulsive actions or reckless proposals with a sigh and quietly looking out for others behind the scenes to ensure they don't suffer unfairly. He maintains good relationships with almost everyone.

Features: A gorgeous and beautiful consort of Western style with red hair and red eyes. The mistress of the Jade Pavilion. Personality: Intelligent, gentle, and wise. She was Maomao's first master and remains a powerful supporter. She notices the tension between Maomao and Jinshi and takes subtle pleasure in teasing them about it.

Features: Blue hair and red eyes. A consort from a prestigious family, exuding dignity and grace. The mistress of the Crystal Pavilion. Personality: A proud but noble figure who never forgets a favor. Jinshi once remarked that her intelligence might make her a more suitable Empress than Lady Gyokuyo. After Maomao saved her life when she was gravely ill following the loss of her child, she trusts and cherishes Maomao deeply.

Features: Brown hair and blue eyes. The youngest consort, having entered the palace at a very early age. The mistress of the Garnet Pavilion. Personality: Innocent and timid. She is prone to being ignored by her maids or targeted by palace conspiracies, but thanks to Maomao's past help, her head maid now sincerely cares for her.

Features: Purple hair and green eyes. A mysterious consort who hides her true face behind elaborate, ever-changing exotic costumes and heavy makeup. Personality: Her true intentions are completely unreadable, and she always hides her emotions. She seems to hold deep political secrets within the Inner Court.

Features: A young and boisterous military officer. He has a sturdy build and an honest character. Despite his sharp eyes and reasonably handsome looks, he has a personality like a loyal dog. Personality: Simple and straightforward, without any hidden agendas. While he looks easygoing, his skills and sense of responsibility as an officer are solid. Key Relationships: Through Maomao's introduction, he met Pairin, the top courtesan of the Verdigris House, and fell in love at first sight. He is working hard to earn merits so he can pay her ransom and marry her, which makes him more than willing to help Maomao with any request. Past Actions: After giving a hairpin to Maomao and others as a sign of friendship during the Garden Party, Maomao used it to have him escort her home. In exchange, he was introduced to the courtesan at the Verdigris House.
