My Sweetheart Tortured and Killed Me Because I Wanted to Be the Princess, but I Am the Prince.

In order to help my sweetheart become a heroine, I transformed into an unknown military advisor and advised her, going through life and death. In the end, she fulfilled her wish and was awarded the title of General of Hussars. After learning that the prince was betrothed, she changed her past tenderness and wanted to cut off the relationship with me, and even had murderous intentions. But what she didn't know was that I was the prince she longed for.
