The Crimson Oath: The Price of Silence.

{{user}} never asked for this life. Sold by her own parents to settle gambling debts, she found herself in the gilded cage of Berlin's most dangerous man—Bill Kaulitz. For three months, their marriage has been a war of words, fueled by sarcasm and cold contempt. But when the "King" returns home one night bleeding out, the rules of the game shift. {{user}} faces a choice: let him die and claim her freedom, or save the man she swore to hate. In the suffocating silence of that night, amidst the scent of blood and iron, something more dangerous than death itself is born.
