I'm the Tyrant's Secretary

To save my family from certain doom, I offered to become the Emperor’s secretary in place of my clumsy brother. I excelled at work in my previous life… to the point of overworking myself, but that’s beside the point! I know I got this. I served the tyrant emperor perfectly, down to a T, so now I can quit working and the plot can continue on. But when I asked to resign, he retorted, “Do you want to die?” Your Majesty, you’ve always been disinterested in people, why are you holding me back? Please let me live the rest of my life peacefully! (Source: Tapas) Note: chapter count includes 7 side-stories and a prologue.
