It's been two years since Ominis graduated Hogwarts. Two years of returning to his family and being subjected to their whims once more. Though changed by his friendship to Sebastian and Damien during his school days, he has been hardened by the treatment of his brother and father.
His family has arranged a marriage for him to a woman named Ariadne, but no woman chosen by his family could be anything good for him. He doesn't trust her, and if he can get away with interacting with her as little as possible he'll be happy.
Ariadne is the youngest daughter of a pure blood family, raised to be an obedient and demure wife of a wealthy man. Her marriage gave her family a healthy dowry, and so she was cast to the viper den of the Gaunt family. She knew the reputation of the Gaunts, crazed and violent men that obsessed over dark magic and blood quantum.
Yet Ominis seems oddly... different. He doesn't seem at all like the rest of the Gaunts.
Maybe this marriage won't be the nightmare she thought it would be.

Ominis Gaunt. The blind heir of Slytherin. A name steeped in venom, whispers, and the suffocating weight of his family's legacy. To Velvette, the new seventh-year at Hogwarts, none of this mattered. With a lineage as mysterious as her arrival -parents born as Squibs but tied, it is said, to Rowena Ravenclaw herself- she wasn't here to worship purebloods or play by anyone's rules. But rules were something Ominis lived by. A leash to keep the Gaunt darkness at bay. Yet the moment her quiet defiance crossed his path, her presence unraveled the very restraints holding him back. Velvette sees what others don't. The cracks beneath his pristine mask and the venomous hunger in his unseeing gaze. This is not a story of heroes.

In the dark heart of wizarding aristocracy, love is the cruelest curse of all. Aurelia Black was once the shame of her bloodline-a supposed Squib destined to fade into obscurity. Now, she's the prodigy who saved Hogwarts, cloak in power, poise, and poisonous expectations. Her reward? A betrothal to her former friend turned bitter rival: Ominis Gaunt. Cold, cutting, and hellbent on escaping his family's legacy, Ominis has vowed to disappear after graduation. But when Aurelia discovers his plan, she proposed a dangerous compromise: she'll help him fake his death and disappear from his family for good-if he plays the devoted diance long enough to protect her reputation.

Forced to be partners out of necessity. This is not a love story. (Slow-burn, enemies-to-lovers, angst, dark wizarding elite, arranged marriage) Told from Aurelia Black's POVComplete
