After the General Died, the Crown Princess Went on a Rampage

I am the empire's Great General Who Guards the Nation. I thought that after returning triumphant from the frontier, I would finally marry my childhood sweetheart and fiancée in a grand ceremony. But I never imagined she had already betrayed me and gotten together with the Crown Prince. All because what she wanted was to be The Outcast, beneath only one person and above all others. Later, I died, pierced by countless arrows on the battlefield. For my sake, she went on a killing spree.
