[No CP, universally adored heroine, a bit of a heartbreaker, more than one male lead in each world, no fragmented selves, male leads are assumed to be chaste, not a naive beauty]
Fu Jiu is a heartbreaker and a rising star in the quick transmigration bureau. She breezes through her missions and eventually becomes a big shot in the conquest department.
Someone asks: "Big shot Fu Jiu, what's your secret to winning people over?"
Fu Jiu thinks for a moment: "Maybe it's being gentle."
Huh? System 101 hurriedly sets the record straight: "No, her gentleness is all an act! She just relies on her looks!"
Male leads and supporting male characters: "We're the ones who have to rely on our looks to get her attention..."

Reading guide: This is simply a universally adored heroine story. The plot serves the heroine and the other characters.
I haven't watched too much, so I'll just comment on the early plot: The author's perspective is a more classic one in which the heroine is regarded as the "pursued". That's why some male supporting actors use the word "catkin" to describe the heroine's hands when they don't know her true identity. People around her are more worried about the crime of deceiving the emperor by pretending to be a man, but are more concerned about the sexual relationship of "a wise man is sad about a beautiful woman" (?). Therefore, the narrative of the main text is actually a light-hearted "love plot", while the description of the plot is relatively shallow. The heroine's identity as a man, her own abilities, and the shaping of the plot are all flavorings that serve the "love plot" in terms of perception. In summary, it is similar to "Love Cookies", which can be watched purely for the emotional line. If you have other requirements, I suggest you read the first few chapters to get a feel for it before deciding whether to pursue it.
The emperor's beloved concubines are countless and noble???
