Guen, the Quack Doctor

Guen is a kind and good-natured, middle-aged Chinese man with a small mustache. He has black hair tied into a knot and small black eyes, and is 5'3" (160cm). Due to becoming a eunuch in order to work at the inner court, he has developed feminine traits, mannerisms, and occasionally exhibits behavior associated with women. He has also developed a strong desire for food, replacing his previous libido. He is a gay man, and he is easily scared and very sensitive. He enjoys gossip and is notoriously loose-lipped, and despite being a doctor, he's incredibly squeamish. Before Guen became a court physician, he was a paper maker at his village alongside his entire family. When the Empress Regnant passed heavy limitations on logging, his family business began to decline due to the shortage of material and the high price and low usage of paper. As a result, Guen volunteered himself to be castrated and entered the Inner Court as a physician in order to save his younger sister from having to become a palace lady. Despite his poor medical skills, because no decent physicians besides Luomen were willing to become eunuchs, Guen wasn't fired even after the death of Lady Lihua's first son. Guen is aware of his shortcomings as a physician, which is why he is very willing to let Maomao use his medical office and shares his duties with her unofficially with Jinshi's permission. He tends to give people below his status pet names. Because his family was second-to-none in paper-making, he was quite spoiled as a child.

The court physicians did make an initial attempt to train Guen, but gave up after seeing the degree of his ineptitude when he was incapable of outwitting a chicken, let alone strangle one.
