There's a tragic novel. I can't remember the name of the main character. I only remember the plot. Can you recommend a similar book?

It seems to be an ancient novel. I read it in a book. It happened in school... The male lead was a killer and the female lead was the emperor, but the emperor had fallen and they began to elope? He ran to the Western Region and found a rose manor. Suddenly, the man received a mission and left. The woman died because of her incompetent father, the emperor. In the end, the male protagonist rushed to the palace and scared him half to death. He wanted him to kneel in front of the girl's grave? I only remember so much about the ending. I can't remember anything else... There was only 40 points, so he couldn't give 40 points, so he could only give 30 points. Everyone, thank you.
I just want to find it. I've seen other things too. It just didn't feel like this book.
