Zhenshi

Main character traits
Pragmatism and caution. Maomao is focused on survival and self-improvement. She avoids unnecessary attention, doesn't seek attachment, and prefers to maintain her distance. In the midst of palace intrigue, she operates on the principle of "the less you know, the better off you are."
Self-confidence and independence. The heroine doesn't need the approval of others. She understands that she doesn't fit into generally accepted beauty standards, and this isn't a priority for her.
Curiosity and a passion for knowledge. Maomao is fascinated by medicine, studying poisons and medicines, and conducting risky experiments, including on herself. For her, this isn't just a scientific curiosity, but also a way to feel alive and numb her emotional pain.
Perseverance and tenacity. The heroine is willing to prove her seriousness and strives to expand her medical knowledge.
Logic and observation. Maomao quickly assesses a situation and constructs a logical chain of events. She has been compared to Sherlock Holmes.
A sense of justice and empathy. Despite her attempts to remain aloof, she cannot ignore injustice. This manifests itself in her intervention in situations such as the illness of her daughter Yang Yuye or the bullying of Lishu.
Restrained expression of emotions. Early in the story, Maomao avoids emotional intimacy and is reluctant to develop attachments.
Trauma-induced traits
Maomao's character was largely shaped by her childhood in the red light district, where cruelty, neglect, and humiliation reigned. Her mother suffered from syphilis and mental illness, and she herself was subjected to physical punishment and emotional coldness. Her adoptive father, a pharmacist, imparted to her knowledge of herbs, poisons, and the treatment of illnesses.

Personality Traits and Motivation
Zhenshi combines external attractiveness and internal tension. Among his traits are:
Confidence and an inferiority complex. He considers himself weaker than his "big brother" (the emperor) and incapable of achieving the heights expected of him.
A tendency to control. The Zhenshi wants to know what's going on in the harem, who's doing what, who's betraying whom, etc.
Calculation and intrigue. He is capable of making quick decisions and using Maomao's (the main character's) knowledge to his advantage.
Playfulness and courtesy in communication.
At the same time, it is important to him that he is considered not only a “handsome eunuch,” but also a person with whom one can work and who can be respected.
Over time, his interest in Maomao evolves from business to personal. He frequently summons her to his office, asks questions, asks for advice, and sometimes violates the boundaries of a "work relationship." Moreover, Zhenshi doesn't simply use Maomao; he's genuinely involved in her life and experiences.
Psychological aspects
According to some interpretations, Zhenshi's character was influenced by his past. He was born to a concubine, whom his father had alienated. Separation from his mother was a torment for the boy, and he may have felt helpless, obliged only to obey, without the right to question or feel.
As he grew older, Zhenshi continued to explore the circumstances of his separation from his mother and learned of his father's vices. This left him with a sense of guilt for his parent's mistakes, a fear of the future, and a dread of his own feelings. He perceives his beauty in two ways: with his mind as a resource, and with his heart as a curse.
Thus, the image of Zhenshi is complex and multifaceted, combining external strength and internal vulnerability, ambivalence and contradictory actions.

Renshi (also referred to as Jinshi) is one of the key characters in The Pharmacist's Monologue, a young man who appears as a handsome eunuch and is in charge of maintaining order in the Inner Court of the imperial palace.
Some appearance features:
Height: about 181 centimeters.
Long dark purple hair.
The eyes are the color of obsidian.
Subtle, somewhat feminine facial features.
A strong build and physical endurance. Maomao notes that his body is "surprisingly well-built," and his hands are smooth and masculine, though calloused from handling a blade.
She wears her hair half-tied into a bun and tied with a cloth.
Usually dressed in the clothes of a court official.
Renshi's appearance is so attractive that just one glance at him can cause both women and some men to tremble. He is described as a "beautiful eunuch."
In public he wears an "angelic smile," but in private he reverts to a more infantile and childish expression.
It's important to note that the eunuch's outward appearance conceals a more complex personality: Renshi belongs to the imperial family—he may be the son or brother of the current monarch. He uses his good looks and charm as part of his influence and a tool to compensate for his lack of outstanding achievements in other areas.
