A Very Proper Arrangement - D.G

Daphne Greengrass only meant to stop one arranged marriage. Instead, she accidentally invented a six-month relationship with Y/N. Now there are family dinners, public appearances, shared rooms and far too much touching for something that’s supposed to be fake. The problem? Pretending to love Y/N is becoming dangerously easy.

Something Permanent

For years, Y/N and Mattheo Riddle had the perfect arrangement: friendship, sex, and absolutely no strings attached. They were careful. They knew the rules. And neither of them wanted anything more. Then two pink lines change everything. Y/N expects panic. Mattheo expects to feel trapped. Instead, he looks at the possibility of a future with her and their child and realises something terrifying. Maybe this was never as casual as they thought. And for the first time in his life, Mattheo Riddle has something permanent worth fighting for.

If You Go, I Go.

Mattheo Riddle takes the Dark Mark and ends things with Y/N to keep her safe. Three nights later, he walks into his first Death Eater meeting at Riddle Manor—and finds Y/N already standing beside the Dark Lord, asking to join them. He chose this life because he believed he had no choice. She chose it because she refused to let him face it alone.

No Grave to Mourn — M.R.

The war ended five years ago. Y/N never came home. Everyone eventually accepted she was dead. Everyone except Mattheo. Five years. Hundreds of dead ends. Not a single day he stopped looking. Then one final lead takes them to a house hidden behind wards nobody was ever supposed to break. And there she is. Alive.

His Fathers Favourite ~ M.R

Voldemort’s favourite Death Eater is everything Mattheo Riddle is told he should be — calm, obedient, precise, untouchable. He hates her for it. What Mattheo doesn’t know is that every perfect report, every carefully chosen silence, and every cold glance hides the same dangerous truth: She’s been protecting him all along. And in Voldemort’s world, caring about someone is the fastest way to get them killed.

You Were Never a Ghost — M.R.

Mattheo Riddle disappeared eighteen months ago. No body. No answers. Just silence. Then Y/N starts seeing him whenever fear sends her magic spiralling. Everyone thinks grief is making her reckless. They’re wrong. Mattheo isn’t a ghost. He’s alive. And somehow, he can see her too.

Leave A Light On.

After years of abuse at home, {{user}} has become frighteningly good at pretending they're okay—even as their mental health deteriorates and thoughts of suicide become harder to ignore. {{love interest}} can't fix them. They can't always understand them, either. But they've known {{user}} long enough to notice when the jokes stop, when the door stays locked, and when “I'm fine” doesn't sound fine at all. This isn't a story about love curing trauma. It's about friendship becoming something more, surviving the nights nobody talks about, and someone quietly leaving the light on so you know you're not alone.

Wait, who’s that?!

Mattheo and Y/N finally become a couple after years of wanting each other, only for a dark curse to erase every memory Mattheo has of Y/N overnight. Now he has to watch everyone else remember the relationship he… can’t, while the Slytherins investigate WHO cursed him and how to undo it before the truth tears them apart. But the times don’t add up, it could’ve only been someone in the Slytherin friend group. Is someone secretly jealous?

I Never Buried You — M.R.

The war ended five years ago. Mattheo Riddle never came home. No body. No grave. No proof he was dead. Everyone eventually stopped expecting him back. Y/N never did. Five years of dead ends finally lead them to a house hidden behind wards nobody was supposed to break. And inside? Mattheo is still alive.

Applications Open | M.R.

Y/n jokingly says she's accepting boyfriend applications. Pansy makes an actual form. Half of Hogwarts applies. Mattheo refuses—then gets suspiciously invested in who makes the shortlist.

I Heard That — M.R.

You thought Mattheo Riddle was just annoyingly observant. Then he started answering questions you never asked. The truth? He’s been reading your mind for months. And somewhere along the way, curiosity became obsession.

DO NOT ADD HER🐍🐍

There are two Slytherin group chats. The normal one. And the one specifically named: DO NOT ADD HER. Unfortunately, Lorenzo adds {{user}}. Right in the middle of a debate about which of her friends is secretly in love with her. And nobody notices until it's much too late.

I’m sorry I’m late, I didn’t want to come.

{{user}} is late to everything, avoids plans she agreed to and would rather be horizontal than socialising. Mattheo Riddle was never supposed to become important—he was just someone hiding from the same party. Unfortunately, he keeps showing up. Now {{user}} has to figure out the horrifying part: how to show up for him too.

The Hour Between.

Every night at exactly 1:13 a.m., Hogwarts stops. The portraits freeze. The staircases fall still. The castle goes silent. At 2:13, everything begins again—and nobody remembers the missing hour. Nobody except Y/N. For weeks, she believes she’s the only person awake in a version of Hogwarts that shouldn’t exist. Until one night, footsteps echo through the frozen corridors. Mattheo Riddle turns the corner. And judging by the look on his face, he’s been keeping secrets about the missing hour far longer than she has. One castle. One impossible hour. Two people who were never supposed to find each other inside it. And somewhere between 1:13 and 2:13, Hogwarts is hiding something that doesn’t want to be remembered

The Spare Key — T.N.

{{user}} only needs Theo's spare room for a little while. Then her clothes are in his wardrobe, her mug is beside his, and everyone keeps asking why they act married. They're just best friends. Obviously. Then Theo starts seeing someone else. And suddenly, “just friends” isn't nearly enough.
