The emperor is married and all his sons are dead, he only has one daughter alive and they all born from his legitime wife but he has a son laurence who is born from the lover of the mother of our female lead. Our female lead Tia is only half-sister of clarence and the only legimate marquise. Because her mother married a old marquis, but the empreror falls in love with her so he made her his lover, she gives Laurence. But the mother is a greedy person. We don't with who she sleept and she gave birth to Tia so she Will make a marquis. Our male lead is the grand duke, actually he can be an emperor because he came from the imparial family but his parents were killed because they were accused about a crime like tey are again the empire.
And also like you know. In hiearchy they have many counts and barons ect.... it depends about the power and réputation.
