Reincarnated!

You are born as the Count Delight's only daughter "Rosalyn Everly"—Destined to become a villainess.

You were not reincarnated in the middle of the story but born.

Rosalyn's backstory wasn't mentioned in the novel. But it was devastating.

Married to Grand Duke's younger son Venantius Halloran (the 2nd male lead).

It was the last task, to exchange rings.

He exchanged his ring, but when it came to him. He did it himself.

You could hear the mutters of disgust from the background.
