Set in the halls of Hogwarts, this story follows Alessia Ambrose and Mattheo Riddle, two elite Slytherins locked in a bitter, seventh-year rivalry. Known respectively as the "Slytherin Princess" and the "Slytherin King," their mutual loathing is legendary-until Professor Dumbledore forces them into a mandatory, year-long academic partnership. As they navigate the pressures of their final year and the weight of their family legacies, their forced proximity begins to unravel years of animosity. What starts as a desperate struggle to coexist evolves into a complex journey of growth, trust, and shared defiance against the expectations placed upon them. It is a tale of shifting loyalties and the discovery that their greatest rival might be the only person who truly understands them.

Reader x Character She fell first, he fell harder..

Rosalie Potter, a Slytherin and Harry Potter's twin sister, had always clashed with Mattheo Riddle. The son of Voldemort, Mattheo was everything Rosalie despised. He was dangerous in a way that drew people in even when they knew better. He ruled Slytherin with a charm that was equal parts infuriating and irresistible. But something in the air shifted this year. Their arguments felt different, the sparks between them harder to ignore. Now, with the pressure of the Triwizard Tournament pushing them together, Rose must confront the possibility that her greatest enemy could become her greatest temptation. Enemies by choice, yet drawn together by forces neither of them could name. TROPES enemies to lovers forbidden love grumpy x sunshine

"You're a terrible liar, Rosier." I looked at him. "And yet you keep asking me questions." Bellum Cordium - War of Hearts Everyone at Hogwarts knows the name Riddle. No one seems to know why one has just arrived. Mattheo Riddle transfers to Hogwarts in his sixth year with a name people recognise and very little interest in explaining himself. Alya Rosier couldn't care less. She already has enough to deal with: her family, their expectations, and the increasingly difficult task of keeping certain things to herself. Riddle, unfortunately, has a habit of noticing. The answers she avoids. The things that don't quite add up. The moments everyone else knows better than to question. And Alya is beginning to notice things about him too. Neither of them particularly appreciates it. With the war drawing closer and old families deciding where their loyalties lie, avoiding each other should be the easiest thing they do. It isn't.

The war is over. Darkness won. One year after Voldemort's victory, the wizarding world survives under careful watch, ehere loyalty is rewarded and defiance is rately seen again. Adeline Ashby has learned how to move through this new world unnoticed-calm, composed, and obedient. But when her future is decided for her and old alliances begin to tighten around her, she is forced to confront a truth she has long tried to bury: some cages are built from duty, others from fear. Mattheo Riddle is the Dark Lord's most trusted enforcer-ruthless, controlled, and frighteningly unreadable. Once, a long time ago, they shared an understanding that needed no words. Now, they stand on opposite sides of the people they have become. In a world where freedom is dangerous and hope is a liability, Adeline must decide what she is willing to sacrifice for the chance at a life she once only dared to dream about. Because even in the darkest timelines...some dreams refuse to die.

❦ Little Trouble❦ In a world where Shadows have secrets, was once a little, cheerful girl who wanted nothing more than to experience a carefree childhood. Till someone decided to change that. She turned from a joyful child to one who wanted nothing more than to be understood. She didn't receive that, which made her into someone who was a perfect target to make fun of. Especially for the infamous boy group. Consisting of Draco Malfoy, Blaise Zabini, Theodore Nott and of course, Mattheo Riddle. The Devil in human form. The son of Voldemort. The darkness that devours. She hated them all her life, wanting nothing more than for them to pay for what they did to her. She was faced with multiple challenges all her life. All that formed her into the person who she is today. Someone who would do everything in their power to get revenge. Maybe even side with her biggest enemy. Will her secrets emerge from the deepest part of her soul or cause her to finally feel understood. ❦The Darkness❦ Beneath the surface, lies a fragile little boy. He dreamt of a normal wizarding family, even envied the ones that got to have that. Faith had something different for him in mind. He learned rather fast that he had no other choice than to obey his father, if not, he would be punished in the most horrific ways. He understood fast that he could not trust anyone, even the ones that he thought were the closest. Not only that, but he grew up and became exactly like the person he never wanted to become. In his 6th year at Hogwarts, he got to see the day when his rival changed. Seraphina Willow Blackwood, a name he always had in mind and never forgot. He didn't understand how someone like her could change into something so... desirable. Especially at Hogwarts was she a walking magnet for all eyes. One day, he stumbled upon a secret he wasn't meant to find. A secret only for Sera to know. Hidden in plain sight, was the secret his father searched for all his life. His Little Trouble.

Mattheo Riddle LOATHES Nora Rosier. In his mind, she's a stuck-up, pureblood brat with a superiority complex granted only by her (admittedly) decent grades. Nora Rosier LOATHES Mattheo Riddle. In her mind, he's an arrogant prick with a superiority complex granted by his infamous father and (admittedly) decent Quidditch skills. Neither of them can stand being in the same room with each other. Well... until THAT night. The night that resulted in a multitude of passions they didn't think they could feel. The night that both of them want to forget but neither of them can stop thinking about. During the day, they go on hating each other as usual. But at night, their bodies explore each other in ways they could hardly dare to dream. It's perfect. Until Nora and Mattheo realize that, perhaps, there's more than hatred in their passion. Perhaps there's even (admittedly) a bit of love. Dusk & Desite is a romance with enemies with benefits to lovers, forced proximity, witty characters, academic rivals, and an infamous Seven Minutes in Heaven scene. It is book #4 in the Slytherin Boys Series but can be read as a standalone. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
