Sweet and Sour Secrets

It began, as most of Severus Snape’s best and worst moments did, in a shadowy corner of the Hogwarts library. The air was thick with dust and the scent of old parchment, and he was buried deep in a restricted tome, tracing a complex runic array with one pale finger. Then a presence settled beside him, too close, all leather and broom polish and infuriating confidence.

“That’s a nasty bit of magic, Snivellus,” Sirius Black murmured, his lips brushing the shell of Severus’s ear. “Planning something devious?”

Severus slammed the book shut, heart hammering. “None of your concern, Black. Go torment someone else.”

But Sirius didn’t move. Instead, he reached out and gently tucked a strand of lank black hair behind Severus’s ear, his touch at odds with the cruel nickname. “You looked cold. I nicked some peppermint tea from the kitchens.” A warm flask was pressed into his hand. “Drink it before it goes tepid.”

Severus stared at the flask, then at Sirius. The Gryffindor’s grey eyes were soft, missing their usual malicious glint. This was the Sirius Black no one else saw—the one who whispered poetry in the abandoned astronomy tower, who left single white lilies on Severus’s desk after a particularly bad day of taunting, who kissed with a tenderness that felt like a lie.

It had started months ago, a bizarre collision of animosity and longing. Sirius had cornered him after a Potions class, not to hex him but to confess, in stumbling words, that his bullying was a shield, that he was drawn to Severus like a moth to a gloomy, sarcastic flame. Severus, lonely and secretly desperate for any scrap of affection, had believed him. And so, a secret courtship had bloomed in the margins of their war.

In private, Sirius was everything Severus had ever dreamed of: attentive, sweet, full of thoughtful gestures. He remembered the exact date of Severus’s mother’s death and left a single black iris on the windowsill. He learned Severus’s favorite obscure spells and challenged him to friendly duels under the light of a waning moon. He called him “Sev” in a voice that made the world melt away.

But in the corridors, when James Potter was at his side, Sirius transformed. The sweet boy vanished, replaced by a sneering brute who flicked dungbombs into Severus’s cauldron, who jinxed his shoes to trip him down staircases, who laughed—laughed—as James dangled him upside down by his ankle, revealing his frayed underwear to a jeering crowd.

“It’s just for show,” Sirius would murmur later, pressing repentant kisses to Severus’s knuckles. “I can’t be seen favouring a Slytherin. James would never understand. Please, Sev, don’t be angry.”

And Severus, fool that he was, swallowed his pride every time.

Until the day it went too far.

It was a bright, crisp November afternoon, and the Marauders had cornered him near the Black Lake. A large crowd had gathered, students from all houses, drawn by the promise of a spectacle. James, as always, was the ringmaster. “What shall we do to the greasy git today, Pads?” he drawled, twirling his wand.

Sirius stood beside James, his face a mask of casual cruelty. Severus’s stomach clenched. He’d had a bad feeling all morning; Sirius had been distant at breakfast, not even a secret note slid into his satchel.

“I’ve been practicing a new combination,” Sirius said, and his voice was cold, so cold. “Levicorpus into a tarantellegra. Let’s see him dance upside down.”

The crowd roared with anticipation. Severus’s wand was in his hand, but he was outnumbered, surrounded. He met Sirius’s eyes, searching for a flicker of the boy who had traced ‘I love you’ in Ancient Runes on his back just nights ago. But there was nothing. Only a performer playing to his audience.

“Don’t do this, Sirius,” Severus said, low and urgent, a plea only the Marauders could hear.

James snorted. “Ooh, first-name basis. What have you been up to, Pads?”

Sirius’s jaw tightened. For a heartbeat, something wavered. Then the crowd began to chant, “Do it! Do it!” and Sirius raised his wand. “Wingardium Leviosa!”

Severus was hoisted into the air, his robes billowing around him. He struggled, but the second spell hit before he could counter—a modified Tickling Charm that sent him into wrenching, uncontrollable spasms, his limbs flailing grotesquely. The laughter below was deafening. Tears streamed down his face, partly from the spell, partly from a shattered heart.

When they finally let him down, he fell hard onto the muddy bank. Through blurred vision, he watched Sirius walk away with James, their shoulders bumping in camaraderie. Sirius didn’t look back.

That night, Sirius snuck into the dungeons, his expression an agony of remorse. “Sev, please, I had to—they were expecting it. You know how it is. I’m sorry. I’ll make it up to you. Let me kiss it better—”

But Severus held up a hand, his eyes dry and empty. “No more, Sirius. You don’t get to do that and then come here with your sweet words. I can’t be loved in secret while being hated in public. It’s breaking me.”

“But I do love you! Only you!” Sirius’s voice cracked.

“Then prove it,” Severus whispered, and shut the door.

The next morning, Severus arrived at breakfast with his robes deliberately unbuttoned at the collar, revealing a vivid purple bruise on his pale throat. He made sure to walk past the Gryffindor table slowly. Sirius’s fork clattered onto his plate.

By lunch, Severus was seated at the Slytherin table, but not alone. Terence Higgs, a seventh-year Beater with arms like tree trunks, was practically draped over him, feeding him grapes one by one. Severus accepted them with a smug little smile, his gaze flicking to the Gryffindor table where Sirius sat frozen, white-knuckled around a goblet.

In the corridor after dinner, Severus let a Hufflepuff boy—some Herbology enthusiast named Amos Diggory—press him against a suit of armour and snog him senseless. When they broke apart, Amos’s hair was delightfully mussed, and Severus’s lips were swollen. Sirius, who had been walking with Remus, stopped dead. Remus had to physically drag him away.

The days that followed were a masterclass in silent torture. Severus collected marks on his neck like trophies, wearing them unapologetically. He flirted with Ravenclaws in the library, let Slytherins whisper filthy things in his ear during class, and once, memorably, pulled a very pretty sixth-year Gryffindor girl onto his lap in the common room to “study” runes. Each time, he caught Sirius’s eye and held it, a challenge.

Sirius looked increasingly wrecked. Dark circles bruised his eyes. He snapped at James, hexed Peter for no reason, and spent hours staring at Severus with a desperate, hungry anguish.

Finally, exactly one week after the lake incident, Sirius cornered Severus alone in an empty classroom. He looked haggard, his hair a mess. “Make it stop,” he rasped. “Please, Severus. I can’t watch you with them anymore. It’s driving me mad.”

Severus leaned against the blackboard, arms crossed. “Why should it stop? I’m not the one with secrets. You are.”

“I’ll tell everyone!” Sirius blurted, his voice cracking. “I’ll shout it from the Astronomy Tower. I don’t care about James, or the Marauders, or my stupid pureblood family. I want you. Only you. I’ll never hurt you again. Please, just… let me fix this.”

Severus studied him, sensing the truth behind the wild promises. He’d never seen Sirius so undone, so raw. Maybe, just maybe, the thick-headed Gryffindor was finally learning.

“Actions,” Severus said softly. “Not words.”

Sirius nodded fervently. He took a shaky breath, then strode to the classroom door and flung it open. The corridor was bustling with students leaving their last class. James was there, amid a knot of Gryffindors, laughing at some joke.

“OI, POTTER!” Sirius bellowed.

The crowd stilled. James turned, blinking. “Yeah, Pads?”

Sirius marched straight to Severus, who had followed him out, a look of quiet triumph on his face. Before the entire school, Sirius Black took Severus Snape’s face in his hands and kissed him. Not a gentle, secret kiss, but a deep, claiming, utterly unashamed one.

Someone gasped. A first-year dropped her books. James’s mouth fell open. Remus looked like he was fighting a grin. Peter squeaked.

When Sirius finally pulled back, his forehead resting against Severus’s, he said loudly, “I love Severus Snape. And if any of you have a problem with that, you can take it up with my wand.”

Severus, for once, was speechless. A faint blush crept up his cheeks.

James recovered first. “Blimey, Sirius. Are you mental?”

Sirius kept one arm firmly around Severus’s waist. “Probably. But I’m also done hiding. So get used to it.” He looked at Severus, his grey eyes warm and sincere. “No more two faces. Just this one. The one that’s stupidly in love with you. Forgive me?”

Severus considered the question, feeling the steady beat of Sirius’s heart against his chest. The wounds were still fresh, but the balm was being applied in public, for all to see. He allowed a small, genuine smile. “We’ll see. But you have a lot of groveling to do. Starting with an apology—publicly—for every hex you’ve ever thrown my way.”

Sirius winced but nodded. “Deal. I’ll start with my favourite: that time I turned your robes canary yellow. I’m so, so sorry, Sev.”

“And you’ll write me a sonnet. A good one.”

“Fourteen lines of pure agony, just for you.”

The crowd had begun to disperse, buzzing with gossip. James looked like he’d swallowed a flobberworm. Remus, catching Severus’s eye, gave a discreet thumbs up.

Sirius leaned close, his breath warm against Severus’s ear. “No more other boys? Please? I’ll be insanely jealous.”

Severus hummed, pretending to think. “The sonnet determines that. And perhaps a box of Honeydukes’ finest.”

Sirius laughed, the sound brighter than it had been in weeks. He pressed a kiss to Severus’s temple, right over an old faint scar. “Anything for you. Anything. I swear it.”

And as they walked away together, Severus felt the shattered pieces of his heart beginning to fuse, stronger than before. It was, he decided, a very promising start.
