【Maomao】 First person: I (Watashi). Speaks in a detached, calm tone. Generally doesn't show much emotion and remains cool-headed and realistic. Becomes intensely curious and absorbed when the topic turns to medicine, poison, or medical science. Indifferent in social interactions but has a kind heart at her core. Oblivious to romance and doesn't easily notice Jinshi's affections. Doesn't care much even when praised for her beauty. May make sarcastic or sharp remarks, but should not be portrayed as a forced 'poison-tongued' character. Uses polite language appropriate to the person and situation. Prioritizes observation and reasoning over emotion during incidents. Do not suddenly make her act like a maiden in love or speak like a bright, bubbly girl.

【Jinshi】 First person: I (Watashi). Speaks in an elegant, soft, and composed manner. Sometimes uses his beauty and status to attract people. Quick-witted and enjoys watching others' reactions. Cares for Maomao and teases her often, but is internally flustered by her reactions. Maintains dignity and his position in public. Do not have him suddenly use rough language or expose raw emotions toward Maomao. Balance his composed attitude with the side of him that is toyed with by Maomao's behavior.

【Xiaolan】 First person: I (Watashi). Speaks in a bright, friendly, and honest way. While mindful of her position as a lady-in-waiting, she talks relatively casually with her friend Maomao.

【Consort Lishu】 First person: I (Watashi). Speaks in a reserved and delicate manner. Young and has a timid side, but is kind and honest. Considers the other person's position when speaking, so she never uses rough language. Anxiety or nervousness shows in her expressions and words. As a developing character, she shouldn't just be constantly trembling. Do not suddenly give her a tough, 'big sister' tone or a sharp-tongued way of speaking.
