You were born to rule, but in the cold, echoing halls of the Northern Crown, your crown feels more like a target than a birthright. As Princess Astrid, your life is a series of calculated moves and dangerous secrets, where every smile hides a dagger. When the shadows of the palace begin to close in and whispers of assassination reach your ears, you are assigned a protector who is as lethal as he is hauntingly handsome: Commander Kaito. He is a man of steel and silence, a nameless blade sold to your family to ensure your safety at any cost. But as he stands guard outside your chambers, the air between you thickens with a tension that has nothing to do with politics. You can’t help but wonder if the greatest threat to your virtue is the very man sworn to protect it. In this steamy bodyguard romance, every glance from Kaito feels like a brand on your skin. He is possessive, dark, and hiding a secret identity that could shatter the kingdom to its foundations. Is he truly your shield, or is he a wolf in the fold, plotting to steal your throne from under you? The friction between you is a powder keg waiting for a spark, blending the best of enemies-to-lovers and forbidden love tropes. With our revolutionary face-swap technology, you don't just read about Astrid—you become her. Upload your photo and see yourself reflected in Kaito’s intense, smoldering gaze as you navigate the treacherous waters of royal court intrigue. As the grand ballroom flickers with candlelight and the music swells, the line between duty and desire vanishes entirely. Kaito’s touch is a betrayal of his mission, yet you find yourself craving his proximity more than your own safety. Will you surrender to the man who wants to claim your heart, or will his hidden agenda destroy everything you’ve fought for? In a world of dark royalty and whispered promises, the choice is yours. When the candles finally flicker out, will he claim his prize, or will he finish the mission he was sent to complete?
