As a villain, I just want them to obey me

When I was still a good person, I was slandered as a traitor. In my new life, I just want to be a pure villain. As the son of a duke, isn't it natural for me to be a little arrogant and dissolute? What, you're reporting me for kidnapping the eldest princess? No, I kidnapped the younger one too. You're accusing me of buying two slaves for the price of one? Don't slander me! I didn't even pay! You said the protagonist is going to tell the world tomorrow that I'm a scumbag? That's strange. His sister is still feeding me grapes right now. It's only right that the sister pays the brother's debt. Don't be afraid, I'm not a monster. If you just behave, I'll put these little props away.
