Lethal Light (Jungkook ff)

Winter Roseburn is the youngest of her family, a spirited and rebellious soul with a strong sense of defiance. Her actions often land her in trouble, but it's no accident. She deliberately challenges her father's authority, not just for the sake of rebellion, but to honor the memory of her late mother, whose death Winter blames on her father's neglect and indifference.
For years, Winter's attempts to gain her father's affection and approval have failed, with her actions growing bolder and her rebellion fiercer. But her father, a man who rules with iron fists, has had enough. Desperate to restore control over his unruly daughter, he devises a plan that he believes will force Winter into submission: an arranged marriage. On the night of Winter's 19th birthday, her father and older brothers announce a shocking and final move. At her grand ball, with guests gathered from all corners of their kingdom, Winter is told she is to be wed to a prince from the distant Leondon Kingdom. Her future husband, Jeon Jungkook, is a prince of great renown, known for his charm, wealth, and power. Winter, who has never before been so easily controlled, can't protest this time. Her father's decision is final, and no amount of defiance will change it. With her life and future now tied to a stranger's, Winter must navigate the intricate politics of the Leondon Kingdom and the growing tension between her own desires and the expectations placed on her.
