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)
