How to Keep an Evil Dragon?

I've always wanted a little dog, all fluffy, who would curl up on my lap and purr, rubbing its damp nose against my face.

That dream can never come true, because I transmigrated into an old castle and got taken in by a dragon.

As the evil dragon's butler, I have to cook delicious food for him and organize his gold. I'm bored to death.

While I was bored, an idea suddenly came to me.

I would turn this evil dragon into my little dog.

It's practically impossible.

It would be so much fun.
