Five years ago, Lee Felix walked away from a love that felt like a wildfire, leaving Hwang Hyunjin amidst the ashes. Now, the fire is back, but it's no longer warm-it's destructive. To save his family from financial ruin, Felix is forced into an arranged marriage with the man he once broke. Hyunjin is no longer the boy who begged him to stay; he is a cold-blooded CEO with a dominant scent that commands submission and a heart that beats for revenge. In a house filled with expensive silence and toxic pheromones, Felix must navigate a marriage that feels more like a prison sentence. The knot is tied, the vows are spoken, but in this house, there is no love-only the debt that must be paid in skin and tears. ________

"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.

In a world of rigid hierarchies, Hyunjin is the anomaly-a powerful Alpha defined by his patience and a genuine desire to protect. But his composure is tested when a political pact forces him into marriage with Felix, an Omega whose ethereal beauty hides a calculated, razor-sharp edge. Felix isn't the "submissive partner" society expects. He is a master of psychological games, using his scent and feigned vulnerability to pull Hyunjin's strings. For Felix, the marriage is a chessboard; he thrives on chaos, weaponizing Hyunjin's kindness against him to maintain control. While Hyunjin strives to build a sanctuary of mutual respect, Felix busies himself setting fires, curious to see just how much it takes to break a "good man." It's a toxic dance of sincere devotion versus cold manipulation, where the greatest danger isn't the forced bond, but the moment Felix starts to enjoy the warmth he's trying to extinguish.
