Survival of a Tyrant's Secretary

Ronaldine is an ambitious woman. When she finds herself as an orphan in a novel she once read, she decides to use her knowledge from the real world to become the best secretary anyone could ever have. Little did she know that her skills would take her all the way to the royal palace--where she becomes the tyrant emperor's personal secretary. Ronaldine fears for her life and wishes to quit her job, but it seems that she is the only person who can calm down the emperor from going on a murderous rampage.
