Sixth year was supposed to be about power - not him. You're a Slytherin with ties to the Dark Lord and a future already written in shadow. But when Mattheo Riddle - your ex and the Dark Lord's son - returns to Hogwarts and becomes your partner for missions, old betrayals resurface and unfinished feelings refuse to stay buried. In a world where loyalty is everything, love might be the most dangerous game of all.

They were everything to each other once - three kids tangled in summer storms, whispered spells, and secrets buried too deep. Then Belle Nott vanished. No warning. No trace. Just silence... and the lie that she was dead. Five years later, she returns to Hogwarts - changed, guarded, and carrying a power even she doesn't understand. But to Theodore Nott and Mattheo Riddle, she's still Belle. The same girl who used to race them through the manor halls, laugh at the thunder, and hex portraits for fun. Only now, her smile is colder. Her silence is louder. And whatever was done to her in the dark... left marks they can't see. They don't care. She's home. And they'll burn the world before they lose her again.

𝐀𝐮𝐫𝐨𝐫𝐚 𝐁𝐥𝐚𝐜𝐤 knows what monsters look like. They take all shapes and forms. She was raised on their legacy. With all her family gone, she learned to survive in the ruins of a life she never got to live. Blame was easy. Hatred was easier. 𝐌𝐚𝐭𝐭𝐡𝐞𝐨 𝐑𝐢𝐝𝐝𝐥𝐞 is the son of a monster. The son of a man she hates. The boy everyone expects to become him. He's supposed to be just like him. But, is he?

COMPLETED 4/4/2021 "The people who often times do terrible things, are the same ones who have had terrible things done to them." After Lord Voldemort murdered Harry Potter in the Battle of Hogwarts, the world became plagued with a darkness unlike anything it had seen before. Muggles were slaughtered in the streets, the Dark wizard's opponents were executed for show, and all those who had fought with the Order were forced into hiding. Avalon had lost it all-- her friends, her peers, her loved ones. Everything. So, when she was thrown back in time to 1943, she knew that it was up to her to change the course of time and rewrite a new history-- one in which she had to find the Horcruxes and murder Tom Riddle before he could ever become Voldemort. Tom Riddle. Avalon Hendrix. Either she was going to kill him, or he was going to kill everyone she loved. They were nothing more than two products of extreme circumstance that chose two very different paths, yet had time for their roads to converge. --Due to the amount of spoilers in the comments, I will be muting all accounts who comment with the #RR hashtag.

Evangeline Lily Potter has always lived in the light. The perfect student, Gryffindor golden girl, and Harry Potter's twin sister - she knows what it means to be watched, to be expected to shine. Stubborn, clever, and just a little too sarcastic, and with ancient magic burning inside her. Then, in her sixth year, he shows up. Mattheo Riddle. The new Slytherin transfer with dark eyes, a dangerous smirk, and a last name that carries enough weight to crush her. Son of the Dark Lord. The boy everyone whispers about. The boy she swears she can't stand. Both with a Legacy written in blood. When their magic collides, Hogwarts holds its breath. They're also opposites in every way - sunshine and stormcloud, Gryffindor and Slytherin, Potter and Riddle. She's the definition of order, he's the definition of chaos. But when sparks turn into fire, and insults turn into late-night conversations, Evangeline finds herself drawn to the one boy she should hate the most. A boy who might be the only person who truly sees her - not "the Chosen One's twin." It's reckless. It's dangerous. It's forbidden. And it might just ruin them both. "A love story that was never supposed to happen."

hatred between a girl and her brother's best friend?

she was an angel with broken wings and never had the chance to learn how to fly. he was a flame born from someone else's match, never taught how to burn, only how to destroy. avaia potter, the slytherin no one saw coming. sharp-tongued, terrifyingly powerful, and entirely uninterested in being understood. a girl with enough magic to bend the world, and too many shadows in her heart to trust herself with it. she doesn't want to be known. he can't seem to look away, even though he despises himself for it. mattheo knows the danger she carries. the kind of storm that swallows everything whole. but something about her fractured soul pulls at the edges of his own. a silent war raging beneath their sharp words and colder silences. neither wants to admit it, but neither can simply walk away unharmed. ──────────────── MATTHEO RIDDLE x FEM!OC

|+18| And then I said; "What was the magic word?" He rolled his eyes. "Fuck off." I raised my eyebrows, crossing my arms. I was definitely going to take advantage of this. "I'm going to kill you-" He exhaled sharply through his nose, forcing himself to shut up. If he pushed me any further, things wouldn't end well for him. He stayed quiet for a moment, biting his cheek, looking around to make sure no one would hear, then; "...Please?" he forced out. My smile widened. I leaned down and slipped back under his arm. He looked at me with pure hatred. "When I recover, I am definitely killing you, Hufflepuff girl." My jaw tightened, but I forced a smug smile. After all these years around his close friends, he still didn't know who I was. He'd never tried. "Don't worry, you won't even remember me when we meet again." But fate would deceive us, and in the worst way possible....

​Everyone knows not to cross a Riddle, especially when a Nott is involved. ​Mattheo Riddle is a weapon-sharp, bloody, and pointed at anyone who looks at Scarlet Nott the wrong way. Their friends call it obsession; the teachers call it a problem. Scarlet calls it home. Scarlet is in denial when it comes to thinking of mattheo is more than friend. How could she like him? They've been friends since they were babies. ​While the Wizarding World waits for Mattheo to follow in his father's footsteps, Scarlet is the only one who sees the boy behind the bloodline. He's the monster under everyone else's bed, but he's the only one who tucks her in. (This story takes place in 6th year)
