The Mad Dog of the Duke's Estate (Novel)

I lived my whole life as a slave, bound by a leash. But there was one thing that I was able to choose for myself: the place where I would die. "..Any last words?" My only friend asked me in a calm voice, and I quietly replied as I closed my eyes. "Waaaah!" ..Waaaah? To cut to the chase, I was reincarnated. And not just as anyone, but as my friend's youngest grandson. So, what am I going to do now? Well, what else can I do? "I’m going to cause chaos.".
