"The first time Y/n bled for him, it wasn't from a knife - it was from a promise, whispered in ink that slithered under her skin like a second set of veins." — A sharp-tongued Slytherin witch stumbles upon a certain cursed diary, only to find herself ensnared in a game of dark magic and dangerous obsession with a younger, far more charming Dark Lord. But as the lines between manipulation and mutual ruin blur, she realizes too late; some pages are meant to be written in blood.
