"Kill him, or crave him. There is no middle ground." A Blood-Treaty signed in ink. A marriage finished in silver. Hwang Hyunjin is the Alpha heir of the North-a man of iron, scars, and a hunger for vengeance. He was born to hunt the undead, not to bed them. Lee Felix is the Last Crimson Prince-a nightmare in silk with ruby eyes and a heart made of ice. He didn't come for a crown; he came to watch the Alpha's legacy bleed. One Bed. Two Enemies. A thousand ways to die. The vows are fake. The hatred is real. The hunger is lethal.

They never meant to fall in love. Hyunjin and Felix were supposed to be just best friends-the kind who could stay up all night laughing, or sit in silence without a single word and still understand everything. Through every change, every distance, every late-night call... they were each other's safe place. But somewhere along the way, something shifted. It wasn't sudden. It wasn't loud. It was quiet, slow, and a little terrifying. Like sparks you don't notice at first-until you realize they've been burning all along. This is a story about friendship, about the spaces in between, and about the moment you realize the person you've always needed has been right there beside you. Always.
