His first appearance is in Chapter 14. He is carrying some plum-wine and accidentally trips, spilling it all over Clove's clothing. Although new, he is a very young and inexperienced servant, only working because his father died in the war. He's the only one that is able to support his family, and he is very clumsy. Yun works as the Empress's informant, as nobody bats an eye towards a child running errands. He is very useful as he can sneak into places others cant. (It is recommended that you look at the comic for context and emotion) Please keep in mind that he is possibly around the age of nine!
