Illicit Affair (mattheo riddle ff)

Illicit Affair

She was never meant to be here. A Muggle-born, thrown into the world of pureblood elitists, trapped in the house of serpents.

Y/N L/N transfers to Hogwarts in her fifth year, placed into Slytherin despite her blood status. She knows she doesn't belong-but she refuses to let that break her. Strong-willed, intelligent, and breathtakingly beautiful, she quickly becomes the center of attention, drawing both admiration and resentment from those around her.

But nothing is more dangerous than catching the eye of him.

Mattheo Riddle. The dark prince of Slytherin. Feared, ruthless, and untouchable. He's cold to everyone, cruel even-but the moment he sees her, something shifts. An obsession is born. He wants her, and Mattheo Riddle always gets what he wants.

Except she's forbidden. A Mudblood. If his father ever found out, she'd be dead before she could even scream.

Still, they can't stay away from each other. Their secret meetings become a dangerous game, a reckless affair fueled by desire and defiance. But in a world where loyalty is everything, and betrayal means death, how long can they keep their love hidden before it destroys them both?
