There was a saying, once, that the line between love and hate is razor-thin. If anyone had ever tried to use Y/n and Draco Malfoy as proof of that, she would have laughed in their face.

Because whatever existed between the two of them wasn’t some harmless rivalry. It was war.

From the moment they met at eleven years old, they seemed destined to clash. Their personalities were simply too large to coexist peacefully. Every conversation became an argument. Every disagreement became a competition. Every shared class became another opportunity to prove who was better.

She thought Draco Malfoy was arrogant beyond belief. Entitled. Smug. Completely insufferable. Draco thought she was infuriatingly loud, impossibly stubborn, and had an irritating habit of always needing the last word.

Neither of them could remember how the rivalry started. Neither of them ever wanted it to end.

They argued so often that it became part of Hogwarts itself, as familiar as moving staircases and enchanted ceilings. If arguing had been a school subject, the two of them would have graduated with perfect marks and enough trophies to fill an entire cabinet.

Their friends certainly thought so. Blaise made a game out of taking bets over when the two of them would finally snap. He’d originally put his money on fourth year. Pansy and Daphne never stopped laughing whenever another blazing row erupted, insisting there was far too much tension between two people who supposedly despised each other.

Astoria was the only one who consistently attempted to keep the peace, usually giving up after five minutes. Theo and Mattheo, meanwhile, never missed an opportunity to point out what everyone else seemed able to see.

One more insult, they’d say. That’s all it’ll take before you’re either kissing or trying to hex each other’s heads off.

Neither of them appreciated the prediction. Yet neither of them ever disproved it.

Their rivalry followed them through every year at Hogwarts. Professors silently prayed they wouldn’t have to partner them together. The library became a battlefield of grades and achievements. Quidditch matches became personal vendettas. Even silence turned competitive, with each of them determined to outperform the other without speaking a single word.

It was never just about winning. It was about proving, once and for all, who stood above the other.

Then came their final night at Hogwarts.

The castle buzzed with the strange mixture of celebration and melancholy that only graduation could bring. Tomorrow everyone would leave. Childhood would be over. Friends would scatter across the country—and the world—to begin careers, apprenticeships, marriages, and lives beyond the castle walls.

Naturally, the Slytherins dealt with the occasion the only way they knew how. By throwing a party.

Pansy and Blaise ensured it was nothing short of extravagant. The common room transformed into a sea of emerald and silver lit by floating candles. Music echoed against the stone walls. Students danced wherever there was space to stand. Firewhisky flowed almost endlessly, accompanied by expensive wines and enough alcohol to ensure nobody would remember every detail by morning.

Neither Y/n nor Draco were particularly restrained.

By the time the night was nearing its end, the room had become hot, loud, and overcrowded. A dancing student stumbled into her. She stumbled into Draco.

Predictably, another argument erupted.

Unable to hear themselves over the music—and equally unwilling to let the other have the final word—they both stormed into the quieter dormitory corridor, still throwing insults with every step. Years of frustration poured out. Every annoyance. Every rivalry. Every competition. Every stolen victory. Every infuriating glance across a classroom.

Alcohol loosened tongues. Tempers flared.

Then something shifted.

Perhaps it was the silence of the corridor. Perhaps it was the firewhisky. Perhaps it was seven years’ worth of tension finally snapping beneath the weight of everything left unsaid. Whatever it was… the next thing either of them knew, their lips had crashed together.

Every insult dissolved into desperate kisses. Every ounce of frustration transformed into something neither of them had ever wanted to acknowledge. Almost without thinking, they stumbled into Draco’s dormitory.

By morning, reality returned.

Y/n woke beside the one person she had spent seven years claiming to hate. Panic won. Before Draco stirred, she slipped quietly from the room, convincing herself it had meant nothing.

Moments later, Draco awoke to an empty bed and told himself exactly the same lie.

Neither of them spoke about it. Neither of them reached out. And within hours, Hogwarts was behind them. Graduated. Finished. Over.

Life moved on.

Y/n excelled during Auror training, quickly earning a reputation for her talent in Defence Against the Dark Arts and her determination in the field. An opportunity with the Italian Ministry was too good to refuse, so while most of her friends remained in London, she packed her life into suitcases and moved abroad.

It was everything she’d dreamed of.

Until, several weeks later, her world turned upside down.

She was pregnant.

There had only ever been one possibility. One night. One mistake. One wizard. Draco Malfoy. Because, apparently, fate possessed an exceptionally cruel sense of humour.

She considered writing to him countless times. She never did. Instead, she chose to raise the child herself.

Months later, her son arrived. Scorpius.

From the moment she held him, every uncertainty disappeared. He was perfect. Soft platinum-blonde hair. Bright silvery-grey eyes. The unmistakable Malfoy features staring back at her before he’d even opened them properly.

If there had ever been room for denial, if she’d ever tried to lie to herself before, it vanished the second she looked at his tiny face. He was Draco’s son. There was no escaping it.

The following four years passed in a blur of Auror missions, sleepless nights, scraped knees, bedtime stories, and countless moments that somehow made every sacrifice worthwhile. Scorpius grew into the happiest little boy imaginable. He smiled at everyone. Trusted everyone. Loved everyone. He possessed an endless curiosity about the world, boundless energy, and a pair of dimples capable of melting even the coldest hearts without even realising.

But balancing life as both an Auror and a single mother became increasingly difficult. The Ministry wanted longer assignments. More travel. More time away from home. More time away from her son.

Eventually, something had to give.

So she returned to Britain. She accepted a transfer to the London Ministry in a role that allowed her to be the mother Scorpius deserved, and for the first time in years, she found herself back among familiar streets, familiar faces, and friends she’d desperately missed.

Scorpius fell hopelessly in love with Diagon Alley the very first time he saw it. His tiny hand remained wrapped around hers as his wide grey eyes darted between crooked shopfronts, enchanted displays, and bustling witches and wizards. He gasped at every owl overhead, every broom in a shop window, every colourful explosion from Weasleys’ Wizard Wheezes. His excitement was infectious. His laughter echoed down the cobbled street. Those little dimples appeared almost constantly.

It felt… like coming home.

To celebrate her return, Y/n arranged lunch with her closest friends at Accioffee!—Pansy, Daphne, and Astoria. Her honorary sisters. The women who had stood beside her through almost every important moment of her life. The women who had absolutely no idea she had spent the last four years raising a son.

She couldn’t wait to introduce them to the little boy who had quietly become her entire world.

Lunch stretched into hours of laughter, stories, tears, and shocked reactions as they met the nephew they never knew existed. Eventually, with hugs exchanged and promises to meet again soon, Y/n and Scorpius stepped back out into Diagon Alley.

She expected many things that afternoon.

Running into him…

Was never one of them.

The bell above the door of Accioffee! chimed softly as Y/n stepped inside, Scorpius’s small hand still wrapped tightly around her own. The café was warm and bright, filled with the rich scent of coffee and fresh pastries. A few patrons looked up from their tables, smiling at the little boy with the platinum hair who was already tugging at his mother’s sleeve.
