I Tried to Twist the Original Story But Ended Up Seducing the Northern Duke

*“I think I’ll… fail if I try to twist the original work?!”* I'd been reincarnated into my favorite romance novel, which I'd reread countless times, even down to the spinoffs. And to top it all off, I was a pathetic, villainous princess who'd been engaged to the crown prince and met a tragic end. To avoid dying, I decided to twist the original story. But... *"I brought you the engagement letter to the Northern Grand Duke, Lily!"* A few days later, this crazy dad arrived with the Northern Grand Duke's engagement letter instead of the crown prince's. *"You've loved me for a long time, Princess."* And he even included a real-life version of the Northern Grand Duke. The bigger problem is... The Northern Grand Duke, the original male protagonist, is determined to seduce me. *"Do you know? How much those eyes confuse my heart."* (Source: Kakaopage, translated)
