Summary
"Never before had he really met a Muggle-born. He had no idea how naïve they were. How unprepared. Certainly, his family said they, and Muggles in general, were inferior, stupid, barely worthy to be at Hogwarts. Barely worth existing. But you weren't any of those things.
You were just afraid."
In which, against the wishes of his staunchly pure-blood supremacist family, Ominis Gaunt befriends you, a naive Muggle-born Hufflepuff, and his life inexplicably changes.
—
Or, what happens when a pure-blood from an anti-Muggle family falls in love with a Muggle-born?
[An adaptation from Ominis’ POV that expands his role in the main questlines and beyond, and parallels his life story with relevant flashbacks. Slow burn Ominis/ReaderOC with Sebastian/MC.]

Summary
"Magical folk didn't follow Muggle customs – strange as it was to adjust – but that didn't mean you didn't think about the future, about marriage. That one day you might like to have a family. That it would be nice to marry someone of your choosing, someone both handsome and kind.
Someone like Ominis Gaunt."
In which, your life changes twice in quick succession: the first, when you discover you have magic, and the second, when you meet an enigmatic blind Slytherin.

Summary
“What do they look like?” he asked into her silence. “Fireworks?”
After a pause, she gathered the tips of her fingers together, touched his forehead, and spread them quickly. “Like flowers in the sky,” she murmured. “Blooming outwards in the most vibrant colours you could ever imagine. Just looking at them makes you feel… hopeful.”

Summary
"The wren and the wraith don't have anything in common, except one thing... they're both trapped."
Sixth-year Ominis Gaunt has no intention of doing anything more than surviving until he's old enough to escape his family, but when chaotic, naïve Muggle-born Tabitha Fulton-Smyth stumbles into his life with no knowledge of the magical world, Ominis proposes an arrangement: he'll help her to better fit in if she'll pretend to be his friend - and stave the unfortunately growing rumours declaring him the true Heir of Slytherin.
But when gossip becomes fate, Tabitha's explosive magic becomes a source of untold mystery, and ruse becomes startlingly too real, Ominis realises that to get the peace he so desperately craves, he'll have to risk it all: his future, his destiny, and worst of all... his heart.
