The Big Sister Transmigrates into a Book: Outwitting and Tormenting the Scumbag

I was a modern-day queen of cool, so who could have imagined I'd end up inside a historical fantasy novel as a villain?

The protagonists are watching me like hawks, and I have no intention of being tortured to death.

Hmph, I'll use modern knowledge and ways of thinking to match wits with them.

Along the way, I meet He Jin, a nobleman who is both capable and outrageously flirtatious.

We fall in love and drive each other crazy, while I work hard to go from villain to someone everyone accepts. And so begins this incredibly satisfying story.
