The halls of Hogwarts were silent this time of night, the only sound the occasional creak of floorboards or the soft wind brushing against the stone walls outside. James Potter had been patrolling—another night of prefect duty—when he saw a figure slumped near a window, head in their hands.

He wouldn’t have paid much attention, probably would’ve assumed it was someone sneaking out past curfew, but the gleam of dark hair caught his eye. He stopped, his heart sinking. It was you.

You and James weren’t friends. In fact, you weren’t friends with anyone, really, except your own family and some Slytherins like Barty, Evan and Pandora. Most people knew to keep their distance from the Black siblings, pure-blooded and cold. You walked with your chin high, always distant and aloof, like you didn’t care about the world around you.

But now, huddled near the window, your shoulders shook with quiet sobs. James hesitated, unsure if he should leave or approach. He wasn’t used to seeing you like this—broken.

Slowly, he stepped forward. “Hey…”

You didn’t respond. Your sobs didn’t falter, and he suddenly felt out of place. He wasn’t supposed to see this—wasn’t supposed to see you like this. But something inside him couldn’t just walk away.

“Black?” His voice was softer this time, unsure, but you still didn’t move. He took another step closer, and that’s when you finally looked up, eyes red and puffy. There was a desperation in your gaze that caught him off guard, and before he could say anything, you shook your head.

“Please…” your voice was hoarse, a whispered plea. “Don’t look at me.”

James froze. He’d seen people cry before, but never like this. Never someone so proud, so unbreakable, shatter in front of him.

You wiped your face quickly, trying to compose yourself, but it was no use. Your mask had already crumbled. You knew James could see everything now—the pain, the hurt, the cracks in the perfect image of the Black family. And for some reason, that made it worse. He wasn’t supposed to see you like this. No one was.

“Look, I didn’t mean to—” he began, but you cut him off.

“Just… don’t,” you choked out, voice shaky. “Please.”

James swallowed hard, guilt flooding him. He could leave, give you your space like you asked, but something in his gut told him that’s not what you really needed.

“What happened?” he asked softly.

You stiffened, staring down at your hands, the silence stretching unbearably. James was about to give up when you finally spoke, your voice barely audible.

“Sirius… he ran away.”

James blinked, his heart skipping a beat. Sirius had only run away from home a few days ago, but he hadn’t told anyone where he’d gone—only that he’d shown up at the Potter’s doorstep with nothing but the clothes on his back. How did you know?

You must have sensed his confusion because you let out a bitter laugh, though it was tinged with more sadness than anything else. “I know he’s with you.”

James’s throat went dry. Of course you knew. Sirius was your brother, after all. But that didn’t explain why you were crying—why the tough, untouchable Black sister had broken down in the middle of a dark corridor.

“He didn’t even tell me,” you continued, voice wavering. “He just… left.”

The words hit James like a blow to the chest. He’d always seen Sirius as invincible, but to you—his sister—Sirius leaving must have felt like betrayal. Like abandonment. And for the first time, James understood. You were left behind to deal with the mess of the Black family while your brother escaped.

You sniffled, wiping your face again, but this time your hands trembled. “I’m supposed to be the strong one. The one who holds it together. But…” You broke off, biting your lip hard, as if trying to stop yourself from crying more. “But I couldn’t. Not this time.”

James crouched down beside you, unsure of what to say. “It’s okay to not be strong all the time,” he said quietly, surprised at how soft his own voice sounded.

You shook your head, squeezing your eyes shut. “Not for me. Not in my family.”

He understood that. The Blacks had a reputation to uphold—a legacy of power, of purity. Emotions had no place in their world.

But you were just a person. A sister who had lost her brother to a world that wasn’t yours.

“I can’t hate him for leaving,” you whispered, almost to yourself. “I just… I just wish he’d told me.”

James’s chest tightened. “He was probably trying to protect you.”

“I don’t need protecting,” you snapped, though the words came out too broken to sound convincing.

Silence stretched between you, the weight of everything pressing down. James wanted to say something to fix it, but he knew there was nothing he could say. Sirius was gone, and you were left to pick up the pieces.

“He’s going to be okay,” James finally said. “I’ll… I’ll look after him.”

You looked up at him then, eyes glassy but determined. For a moment, the vulnerability vanished, and you were the strong, unshakable Black again. But this time, James saw beneath it. Saw the hurt that came with that strength.

“Promise me,” you said softly. “Promise you’ll take care of him. No matter what.”

James nodded, his voice firm. “I promise.”

Your shoulders slumped in relief, but the sadness in your eyes didn’t fade. You stood slowly, brushing off your robes like nothing had happened, though the cracks were still there, visible to him now.

Without another word, you turned to leave, but before you walked away, you paused, looking back over your shoulder. “Thank you,” you whispered.

James opened his mouth to respond, but you were already gone, disappearing into the shadows of the corridor, leaving him alone with the weight of your words.

He’d keep his promise. For you, for Sirius. Because now, more than ever, he understood just how much it mattered.

Warnings ~ Beginner level writing, angst, mentions of evil Walburga and Orion (they can literally just leave), Remus being a sweetheart, unedited

Note From Mia ~ Second time writing on here....I hope you like it, but I understand if not lmao

You had always been more on the reserved side. Where Sirius had chosen to leave the tortures from 12 Grimmauld Place behind him when the Black Siblings returned to school, you and Regulus had been the opposite.

You couldn’t forget. It wasn’t possible. The horrors you always faced at home haunted you every night, leading into early in the mornings, leaving you restless the rest of the day. The only peace you got was when you could sneak off into the library to bury your nose in whatever book you had your hands on. Whether that was a reread or a completely new genre, it didn’t matter. It was an escape.

So, that is exactly what you were doing now. You had been curled up in an armchair in a secluded corner of the library, reading, for almost an hour now. No distractions. Mind blank. Peace finally washing over you.

Letting out a soft sigh, you flipped the page, getting ready to read another chapter when a shadow loomed over you.

“Hello, Dove,” Remus whispered from above you. “Having a bad day?”

You and Remus had met in the Library on a rainy afternoon, and just sat together in silence while reading. Over time you had started small talk, and that led to conversations, which then led into a friendship, turned secret relationship.

It’s not that you wanted it to stay a secret, however, Remus and you were both scared of backlash from Sirius, and you were terrified of your parents; therefore, they could never find out.

Remus notices that you’re too far, too deep into your book to notice him. To pull you back into the present, he carefully rests a hand on your thigh and rubs gently, coaxing you back into the real world.

You flinch slightly at the contact before looking up to see your boyfriend. “Oh, Rem, hi. How long have you been there?” You ask, shutting your book to give him your undivided attention.

Remus ignores you, smiling gently, not sympathetically though, because he knows by now that you won’t accept it. “What do you need from me, Dovy? To talk?” He’s more than aware that you are not actually going to open up right now, he can see it in your eyes from a mile away.

“Can you just hold me?” You whisper, your words laced with vulnerability. 

Remus’s eyes soften before he shuffles you around, sliding onto the chair behind you, and situating you onto his lap. He doesn’t say anything. He just holds you, gently stroking your hair, occasionally leaving a kiss to the crown of your head. 

When he thinks you're almost asleep, you speak again, “Nothing ever lasts forever, Rem.”

“I know, love. What are you referring to?” He asks, dread filtering into his mind. The lycanthrope has a love-hate relationship with your deep thoughts. Some bring on deep meaningful conversations, whereas others are filled with unnecessary insecurity and doubts.

“Us,” You mutter the exact words that he was dreading.

“No.” Remus says sternly, a tone you rarely hear him use. “I will always love you,” He turns you so you’re sitting sideways in his lap, him making direct eye contact with you, making sure that you hold it. “We’re not doing this, you need to get rid of whatever negative ghosts that are haunting your mind, because we are not breaking up. If I need to help chase those ghosts away, then so be it, but you cannot let them dictate our relationship. Ours, not theirs.”

You nod, burying your head into his neck, breathing in the calming scent of cocoa and old books, mixed with a hint of pine. 

“I want to hear you say it,” He whispers, nudging you with his shoulder.

You lift your head from the crook of his neck and smile weakly. “Ours, not the ghosts.”

“Exactly right, Dove.”

Remus leans in and gently presses his lips to yours, and you reciprocate before he leans back, pulling you into his chest. “I love you,” He whispers, again, knowing you needed reassurance. “And I always will.” 

You nod, “I love you, forever and always.” It comes out in a whisper, but Remus hears it anyway and presses his forehead against yours, but not before pressing a kiss to your nose.

He slowly reaches up and presses the pads of his thumbs where he knows your dimples are and where he knows they should be right now. “Can you smile for me, Love?”

And you do. Because you love him, more than you thought you were ever capable of. You smile crookedly, showing Remus that it is indeed a true smile, and he leaves a kiss on both dimples before pulling away and smiling back at you.

You bring your own thumbs to his face, rubbing gently over the hundreds of freckles scattered along his face.

He kisses you gently once more before grabbing your book, “Now, what were we reading before I interrupted?” He questions teasingly. 

“Well, I was reading that,” You admit sheepishly, pulling out a quill and ink container from your bag.

“The Wonderful Wizard of Oz?” Remus raises a teasing brow.

“Oh hush,” You shove his shoulder. “I was in the mood for something different and it was in the muggle book section. It seemed interesting.” 

“No judgment from me then, Dove.” He whispers, opening the book at your marked spot.

And that is exactly how you and Remus spend the rest of your day. Him reading to you, and you drawing thin vines, small flowers, and a variety of constellations on his various scars while you listen to his soothing voice tell the story of a girl with a dog that somehow got sucked into a tornado and transported into the world of Oz. It didn’t make sense to you, but Remus was reading it, and that was all that seemed to matter to you at that very moment.
