Description
Maomao possesses a petite frame with striking dark forest green hair and blue eyes. She typically secures her hair with a light blue ribbon, allowing two strands framed by red and sky blue beads to fall beside her face. Deliberately cultivating a plain appearance, she often paints temporary freckles near her nose bridge using clay or needle-based tattoos. A bandage on her left forearm hides self-inflicted scars from testing poisons and remedies. She favors simple, practical clothing: an aoqun hanfu comprising a light green top, burgundy skirt, white inner robe, and dark green flats. On rare occasions without her freckles and in elegant dress, her striking beauty causes others to fail to recognize her.

Her pragmatic, emotionally detached personality and strong survival instinct stem from her red-light district upbringing. She views relationships transactionally, avoids deep attachments, and prioritizes self-preservation, believing people are expendable based on status or circumstance. This worldview formed after witnessing courtesans discarded when deemed valueless and her mother Fengxian's tragic decline from syphilis following abandonment by a patron. Fengxian conceived Maomao to lower her own price for this patron, who vanished, leading to poverty, disease, and abuse directed at Maomao—including the severing of her pinky finger. Despite her aloofness, an insatiable curiosity and latent sense of justice drive her to intervene against injustices like Consort Lishu's mistreatment or infant poisonings. She remains largely unmoved by Jinshi's renowned beauty and charm, viewing his romantic advances with skepticism due to the complications they would introduce.

Trained in pharmacology by her adoptive father Luomen, a skilled physician, Maomao specializes in poisons and medicinal herbs. She frequently self-administers substances to study effects, building significant resistance to toxins, alcohol, and hallucinogens—though not to her buckwheat allergy. She applies similar principles to cooking, creating dishes like chocolate bread and grilled snake. Her acute perception and deductive reasoning, honed in the red-light district, solve palace mysteries. She is agnostic or atheistic, rejecting superstitions for scientific explanations.

Raised in the Verdigris House brothel, Maomao learned early that emotional connections create vulnerability. Key figures include Luomen, her medical mentor, and the "Three Princesses" (Pairin, Meimei, Joka), whom she considers sisters. After being kidnapped and sold into imperial palace servitude, she planned an anonymous term but was drawn into intrigue after solving the illness of Consort Gyokuyou's daughter. This brought her to Jinshi's attention; he leveraged her fascination with poisons by offering rare medicines in exchange for her investigative skills.

Her development shows gradual emotional engagement despite initial resistance. She forms reluctant bonds with consorts like Gyokuyou and Lihua. Her dynamic with Jinshi shifts when physical contact during an assassination attempt reveals his secret: he is not a eunuch but the emperor's son, concealed through suppressants, altering her perception of him. She also confronts her biological parentage; her father is military official Lakan. She challenges him to Chinese chess, staking her living with him if he wins or his purchase of the courtesan Fengxian if he loses. His defeat leads him to redeem Fengxian. Later, Suirei abducts Maomao, threatening violence against Shisui (Consort Loulan) to coerce cooperation. During this ordeal, Maomao deduces Suirei and Shisui are sisters and that Suirei knows of Lakan's paternity, viewing Maomao as leverage against him.
