what about a hero/villain arranged marriage?
1) It was their wedding night. Doors shut, no witnesses, all the arrangements made and the knots tied as surely as a hangman’s noose. The hero swallowed, hyper aware of the large bed dominating the room behind them. Their hands trembled.
The villain leaned back against the door, looking them up and down with a smile of slow appreciation. “All mine. Just as I promised you that you would be.”
“You can cage a creature, that doesn’t make it yours,” the hero spat. “This isn’t over.”
“No,” the villain said. “Not yet.” They peeled away from the door and stepped closer, letting their jacket drape on a chair. “There are still some traditions for tonight, hm?”
2) “Not what you expected?” The villain smiled, frosty. “I had plans other than you too. I suppose we’ll both have to make do.”
The hero drew back, wide-eyed, because no. This was not what they’d expected at all. A little awkwardness, a little chill, not a dead body on the bedroom floor. “What are you?”
3) “Don’t worry.” The villain caressed their partner’s cheek, down along the oh so vulnerable line of the hero’s throat. “I won’t hurt you. Suspicion always turns to the spouse first in these things.”
“And then where would that leave you? Like it or not, love, I’m all that you have in the world now. We need to look after each other.”
