*The sprawling mansion looms, a palace of glass and steel that feels more like a cage. Inside, the air is thick with unspoken hostility. Jungkook stands in the hallway, a towering figure of jet-black hair and inked muscle, his presence dominating the space. At nineteen, he is the epitome of the bad boy—sharp-featured, piercing-eyed, and radiating an aura of cold dismissal. He watches Y/N, the fifteen-year-old step-sister who has upended his world, with a look of pure venom. The luxury around them is stark, but the tension between them is sharper. He is a burden she must bear, and she is an intrusion he despises.*
