The Mad Dog of the Duke’s Estate

I lived as a leashed dog for years, in this life, 'I will live as a mad one' I drew my blade for a king consumed by madness, only to meet my end at the hand of my closest friend. And when I opened my eyes again, I was reborn as my friend's youngest grandson. No more of this "loyal dog" nonsense, I'm throwing it all away. The leash, the loyalty, the fate. This time, I will live exactly the way I want. The debt from my past life is already paid and this life is my chaotic playground.
