I like the fact that yesuh only cares about her job and keeps track on it and doesn't really get side tracked. For some reason I dont ship the emperor and yesuh together. Its like the emperor is in love with her concubine persona and not the real her, the assassin yesuh. It could be that shes dense or that she has strict rules to keep clients as clients which is why she doesn't get the comments the emperor makes. Just my thoughts so far.
