Cant find this one and its annoying since my memory of it isnt the best. Maincharacter is a girl. Somehow she get hired in the palace. Medical apprentice or something. The emperor is masked and has a hidden identity. Think is due to assasination attempts. Seriously cold blooded dude. Think he even had some not so nice nickname. Other than that I remember some flirty general and a white haired dude. At some point I think I suspected the general being the emperor.....
