Since When You Were the Villain?

She was possessed by a book without knowing what novel it was. Then, one day, her fiance appeared. ‘Killian’ was a perfect Northern Duke with black hair, red eyes, and a handsome face. It was a contract marriage. ‘I can see that person is the male protagonist even if I rolled backwards…’
So, Sophia believed without a doubt. She thought he would be the male protagonist. But…
“Ah, I got caught.”
The smell of blood came on the tip of her nose. Killian’s eyes narrowed. Then she realized the fact that he was a villain.And a cold hand caressed her cheek.
“There won’t be a breakup, Sophie.”
Raising the corners of his lips slightly, he whispered softly. ‘I think this is also a cliché… I hate that cliché!’
