A Happy Ending for Villains (Promo)

I was reborn into a romance fiction novel. I am lowborn, but there are plenty of boys here, and I get to work for the nobles. But there’s a tiny problem. This noble family happens to be a family of villains, and I’m supposed to lead these serpents and throw the empire into chaos. Apparently, I am the greatest villain in this novel! The deaths, the chaos in the empire, and the matters of inheritance locked the duke’s children and me into a corner of the manor. But the novel never mentioned anything about being locked away. So here, I must survive and grow… for a villainous happily ever after.
