Bound to the vampire I must kill

She was an assassin, the princess of the witches, sent to marry the Vampire King with one purpose—to kill him and secure her clan’s victory in a war that has raged for centuries. He was Rhydian, the brooding king burdened by his father’s bloody legacy, forced into the alliance to protect his people from the looming Dragon Empire.

Rhydian distrusts the witches, while Seraphina resents the vampires, but neither is prepared for the sparks that fly when they meet. As they face palace intrigues, ancient prophecies, and brewing rebellion, their hatred begins to shift into something neither expected—love.

But their union comes at a price. With dark forces plotting to tear them apart and a greater danger threatening both their worlds, they must decide: will their love save their kingdoms or destroy them all?

I won't call this enemies to lovers but it's kinda similar, I don't know yet if I'll make it slow burn, but we'll see as the see how this progresses. it will contain some R18 contents, I'll always highlight that for every chapter, so you can Skip of you want. Note: They are both cold hearted. so it might take a while for both of them to accept their feelings.
