{ Chapter 1 }

Chapter Text

The mansion was always too quiet, polished marble floors echoing each tentative step, silk drapes smothering the outside world. (Y/n)’s mother’s delicate hands would flutter over her shoulders like nervous birds, adjusting her collar, smoothing her sleeves.

“You mustn’t strain herself, darling." Her voice was honey laced with poison—soft, sweet, but suffocating. The doctors said her body was frail, but was it truly frail…or just starved of use?

Servants carried trays she wasn’t allowed to lift, books she wasn’t permitted to open without supervision. Even the garden, vibrant with roses her father once planted, was forbidden. “The thorns might prick you." But thorns were nothing compared to the slow erosion of being treated like glass.

Then came the night she slipped through the servant’s entrance, the crunch of gravel under stolen boots louder than her pulse. Freedom tasted like dust and desperation, until the world showed her how cruel it could be.

The harsh realities of the world weighed on (Y/n) like a leaden collar. Several days of people shoving and pushing her out of the way on the crowded sidewalks. They threw glances of contempt and revulsion at her dirty clothes and unkempt appearance, as if she was an unwelcome blemish within their perfect society.

"Out of the way, street rat!" One person spat, shoving her to the ground.

She stumbled and fell, landing harshly on the pavement. Her ragged clothes and dirty face made her look even smaller and more vulnerable. Several people passed by without even sparing her a second glance, but a few stopped and watched with amused smirks on their faces.

"Look at this pathetic little thing." A woman sneered, her eyes filled with contempt.

"Shouldn't you be back in the gutter, where you belong?" a man snickered.

Tears welled up in (Y/n)'s eyes, but she refused to let them fall. She pushed herself off the ground, dusting off her knees and straightening her spine. Though her body quivered with fear and humiliation, she met the gazes of those who jeered at her with a cold glare.

Her numb indifference was an odd contradiction, an inner strength that surprised even herself. It shielded her from the full force of their insults, letting them wash over her like waves over stone. She knew they were right. She didn't belong here. But a small, stubborn part of her refused to give in completely.

“Please….leave me alone. If I bother you so much….then just ignore me” she muttered.

The people jeering and mocking her paused, their smirks faltering slightly at the mention of her clothing. They took a closer look at the fabric and design of her clothes, a realization slowly dawning on their faces.

"Hold on a moment..." a man said, his eyes narrowing. "These clothes...they look too good to be from a street rat."

Their expressions shifted from mockery to something darker, greed flickering in their eyes. The woman who had sneered earlier stepped closer, fingers twitching.

"Could be stolen..." she mused, voice lowering. "Or perhaps she's a runaway. Either way... that fabric's worth something."

A hand suddenly snatched at (Y/n)'s sleeve. The sudden grip shocked (Y/n), her heart leaping into her throat as a gasp escaped her lips.

Adrenaline flooded her veins, awakening a primal survival instinct. The person holding her sleeve was a man, his face twisted in a cruel grin.

"No use struggling, little missy. You and those fancy clothes of yours are coming with us."

Just as fear threatened to paralyze her, a deep voice cut through the tension like a whip:

“Unhand her."

A figure stepped from the crowd—tall, commanding, with piercing blue eyes that burned with quiet fury. The man gripping (Y/n) froze, recognizing him instantly: George Joestar, patriarch of the Joestar family.

"T-this doesn't concern you, sir—"

“It does now." George's gloved hand closed around the man's wrist with terrifying precision.

“Walk away. Or I'll ensure you never use this hand again."

The crowd scattered like roaches in sunlight.

(Y/n) stared up at her unexpected savior, breath ragged.

Her wide eyes took in George Joestar’s stern but not unkind expression. His grip on the thug’s wrist remained firm until the man yelped and scurried away with his companions. Then, George turned his full attention to (Y/n), his gaze softening just slightly.

“Are you hurt?" he asked, his voice carrying an authority that demanded honesty.

(Y/n) swallowed hard, shaking her head mutely. The kindness in his voice, felt so foreign after months of cruelty. It made her throat tighten.

George studied her for a long moment before sighing. “Come. You’re coming with me."

And for the first time in what felt like forever... she didn’t resist.

As George led (Y/n) away from the scene, she couldn't help but notice the way passersby hurriedly moved out of his path. He moved with a confidence that only came from influence and power, and it was as intimidating as it was comforting. He guided her towards a waiting carriage, his hand resting lightly on her shoulder.

“Get inside."

She obeyed quietly, sitting on the plush interior and looking around warily; the luxury was almost overwhelming. George followed, and the door closed behind him with a soft click.

The carriage smelled of aged leather and cedar, a stark contrast to the filth she’d been living in. George didn’t speak as it began moving, his sharp eyes studying her, as if piecing together a puzzle.

“Your name," he finally said, not unkindly but with expectation.

(Y/n) flinched slightly at the command. Her voice came out quieter than she intended: "...(Y/n)."

George’s brow twitched, not quite approval, not quite surprise. His gaze flickered to the tattered fabric of (Y/n)’s sleeve where it had been torn by thugs moments ago.

“You're from money." A statement, not a question.

He exhaled through his nose, a slow sound that carried more weight than frustration. His gloved fingers tapped once against the carriage wall, deliberate, and measured.

“A runaway then." His eyes darkened slightly. “Your mother let you go like this? Or did she throw you out?"

The question was sharp. Not an accusation, an assessment. George had seen too many "proper" families discard their own.

(Y/n)’s hands curled into her sleeves reflexively as if to shield herself from the truth of it all. The silence stretched too long before George clicked his tongue and leaned forward abruptly.

He observed her fists, the stiffening spine. He recognized the flinch of memory, the bitter twist of the mouth.

“She threw you, then." His tone was flat, the conclusion clear.

(Y/n) swallowed, her eyes suddenly prickling.

She wanted to argue, to defend the woman who'd sent her into the streets. But this man—this stern, cold stranger, saw something in her that made her protests seem more like childish denial.

“No…she didn’t. I…ran away because I got tired of being her doll….”

George's stoic expression didn't flicker, but the sharpness around his eyes softened a hair's breadth. It was a subtle change, but his tone became less stern. He leaned back against the leather of the seat, a quiet sigh escaping.

“Her doll." A quiet scoff. “And if you stayed, she'd have stuffed you onto a shelf and only pulled you out when it was convenient." He didn't even phrase it as a question.

As if pulled by a string, (Y/n) nodded slowly. George's words echoed painfully through her mind, each one striking a nerve. A doll. A toy to be played with.

A thing, not a person. In the back of her mind, she heard her mother's voice: "You're too weak, (Y/n); fragile, like brittle porcelain. You aren't made for this world." The memory ached like fresh bruises.

George exhaled sharply through his nose, his jaw tightening briefly before he spoke again, this time with something resembling approval.

“Then you chose freedom over comfort. That takes spine." His gloved hand gestured dismissively toward her tattered clothes.

“But surviving out here alone? Reckless. You've got grit, but grit without a plan gets people killed."

The carriage rolled to a smooth stop. George didn't wait for her reply as he pushed the door open, sunlight spilling in.

“Come. You'll stay at the Joestar estate, for now."

It wasn't an offer. It was an order. (Y/n) hesitated only a moment before stepping out...and into a new life.

The carriage had pulled up to the main gate of an immense estate, sprawling across multiple acres. The lawn was perfectly trimmed, hedges precisely manicured, and flowers growing in colorful patterns. But the most imposing feature of all was the mansion itself, an impressive manor of pale stone with white walls and tall arches.

Dozens of windows glittered in the sunlight like jewels, and the place emanated an almost regal air. George gestured for her to follow him up the gravel path.

She obeyed in silence, eyes wide as she took in the sheer scale of the manor. The gravel crunched underfoot, their pace unhurried yet steady. In the distance, the muffled voices of gardeners and maids drifted through the air.

(Y/n) caught whispers of "Sir Joestar", tinged with respect and perhaps a hint of nervousness. It was clear that everyone here held George in high esteem.

As they approached the grand entrance, a pair of double doors swung open. A butler, an older gentleman with salt-and-pepper hair, stepped out and bowed deeply. His eyes flicked to (Y/n) for a brief moment before he spoke with a crisp English accent.

“Master George. Welcome back. And...you have a guest, I see."

George nodded in acknowledgement, his strides unfaltering as he crossed the threshold. The interior was just as impressive, if not more so, than the exterior.

A sweeping spiral staircase led up to the next floor, and oil paintings depicting historical Joestar family members adorned the walls. Their footsteps echoed softly in the vast entryway.

“This is (Y/n). She'll be staying with us for the foreseeable future."

The butler—Alfred, his name was, raised an eyebrow at that.

Alfred's eyes darted to (Y/n)'s ragged clothes and hollow cheeks, lingering just long enough to assess without being overtly rude. His expression remained professionally neutral as he gave a shallow bow.

“Very good, sir. Shall I prepare the east guest room? Or...perhaps something closer to young Master Johnny's quarters?"

George's lips thinned slightly at the mention of his son. His reply was clipped.

“East wing. For now."

Alfred nodded briskly and turned to (Y/n), his tone softening a fraction.

“This way, Miss (Y/n). A bath and fresh clothes will be arranged immediately."

(Y/n) hesitated, glancing back at George, but he'd already vanished down the hall, his coat flaring behind him like the wings of a retreating hawk.

Alfred gently guided (Y/n) upstairs, his pace measured to match her hesitant steps. The east wing corridor was lined with portraits, stern-faced Joestars from generations past seeming to judge her from their gilded frames.

“Pay them no mind," Alfred murmured, noticing her uneasy glance. “They were all troublemakers in their youth too."

A maid waited by an oak door, arms folded neatly over her apron. At Alfred's nod, she curtsied.

“Hot water's drawn, miss. And..." She held up a simple but well-made dress, ivory with pale blue trim.

“Something that might fit."

(Y/n) reached out, fingers brushing the fabric. It was soft. Not silk, practical cotton.

For the first time since running away, she felt seen.

After her bath, her damp hair clung to her shoulders as she walked out in time to overhear George talking with someone. She lingered near the doorway, listening intently. The horse—George mentioned its name was Black Rose, was suffering from a fever, and his son Nicolas was fretting over its condition.

“Father, the stablehand says he won't last the week if we don't—"

Before Nicolas could finish, (Y/n) stepped forward without thinking. “Can I see him?"

Both men turned, surprised by her sudden interjection. George's brow arched slightly, but Nicolas, who had inherited his father's sharp features but none of his restraint, looked downright skeptical.

“You? What could you possibly—"

George silenced him with a raised hand.

“Why?" he asked simply, eyes locked onto (Y/n).

She swallowed hard, fingers twisting into the fabric of her new dress. "...I just...want to try something."

They both pondered in silence, before George spoke up.

“Very well." George gestured toward the stables. “But if Black Rose so much as startles at your presence, you leave. Understood?"

(Y/n) nodded eagerly, already moving toward the barn before they could change their minds.

Inside, the air smelled of hay and medicine. Black Rose, a magnificent chestnut stallion, lay in his stall, breathing labored. His dark eyes flicked to her weakly as she approached.

“Easy, boy..." she whispered, not in English, but in something softer and older.

Black Rose ears twitched. His nostrils flared. And for the first time in days...he lifted his head.

She smiled softly before whispering in its ear. “It’s okay, I won’t hurt you. In fact, I can understand what you’re saying. So…can you tell me what’s wrong?”

Black Rose let out a weak but understanding huff—his breath warm against her cheek. His dark eyes blinked slowly, tired but trusting as he answered in a language only (Y/n) could comprehend, a whisper of pain, of stiffness in his joints, of a fire burning beneath his skin.

She nodded and turned back to George and Nicolas, the latter staring in utter disbelief.

“It's not just a fever," (Y/n) explained quietly. “His leg is inflamed from an old injury that never healed right. The heat is spreading through him like poison."

George's expression remained unreadable, but Nicolas scoffed.

“That's impossible! How could you possibly—"

(Y/n) ignored him, already scanning the stable for herbs—rosemary, comfrey, anything with anti-inflammatory properties.

Her fingers twitched with purpose. And for the first time in her life, someone needed what she could offer.

George watched with a subtle intensity, his gaze never leaving (Y/n) as she moved around the stable. His eyes narrowed, a hint of curiosity in his expression as she began gathering the herbs.

“What is she doing, father?" Nicolas murmured, watching (Y/n) with a mix of skepticism and disbelief.

“Just wait," George replied quietly, gaze locked onto (Y/n). "...And watch."

With practiced hands, (Y/n) crushed rosemary between her palms, releasing its sharp scent before pressing the bundle gently against Black Rose’s swollen leg. The stallion tensed, then relaxed with a shuddering exhale as the cooling sensation seeped into his inflamed flesh.

“See?" she murmured, not to the Joestars, but to the horse. “Better already."

Nicolas stiffened when Valiant suddenly tried to rise, his hooves scrabbling against the straw. But it was George who stepped forward first, his sharp eyes widening slightly as the stallion, who had refused even water for days, now nudged (Y/n)'s shoulder affectionately.

“Remarkable," George admitted, the word leaving him like a reluctant confession.

(Y/n) smiled faintly, stroking Black Rose’s muzzle, but her fingers trembled. She hadn't realized until now...how much she'd missed being useful.

She then busied herself tidying the stable. Her back was turned as she picked out the soiled straw, but even so…the intensity of the two men's stares felt palpable. She could sense their scrutiny, and it took all her willpower to keep her expression even.

Eventually, she turned back to face them, and found herself pinned by George's steely gaze.

“Tell me how you knew what was wrong with the horse." he said bluntly.

“I-I don't know," she stuttered, suddenly defensive. Her fingers twisted into the fabric of her dress.

Her eyes flickered to Nicolas, who looked almost disappointed. She could almost hear the "I told you so" on the tip of his tongue.

But to her surprise, it was George who cut across the heavy silence.

“Try again." His eyes flitted over the herbs and ointments she'd used, sharp and considering.

“….m..me and my father….when he was still here….cared for animals deeply and he taught me how to treat them”

George studied her for a long moment—calculating, dissecting. Then he gave a single slow nod.

“Your father trained you well." He turned to Nicolas, his tone leaving no room for argument. “See that Valiant gets fresh water and extra feed tonight."

As Nicolas reluctantly moved to obey, George fixed (Y/n) with one last assessing look.

“You'll tend to the estate horses from now on. Consider it your responsibility." He paused, then added, almost as an afterthought.

“And you'll dine with the family this evening."

With that, he strode out of the stable, his coat billowing behind him, leaving (Y/n) standing there, heart pounding with something dangerously close to hope.

“Father? Who is this?” George’s younger son, Johnny, spoke out as he approached them from the mansion back door.

George cleared his throat, breaking the tension with the same effortless authority that seemed to command every room he entered.

“Johnny, this is (Y/n). She'll be staying with us indefinitely." His tone left no room for debate.

“Treat her as you would any member of this family."

For a moment, (Y/n) couldn't find her voice. The whole situation felt surreal. Just this morning, she'd been continuously fleeing her old life, and now she was what? Adopted into the Joestar family? It would've been laughable if it wasn't so crazy.

Johnny blinked, glancing between his father and (Y/n), then, surprisingly, a slow smirk tugged at his lips.

“Well...guess that means I can blame her when I skip lessons now."

The joke caught (Y/n) off guard. A startled laugh escaped her before she could stop it, and just like that, the weight in the air lifted slightly.

Nicolas scowled, his mouth opening to protest, but he fell silent as George fixed him with an icy stare. He swallowed, jaw clenching before he stormed off to do as he'd been told.

Later on, she steadily became adjusted to her new family and life, until later in the night.

(Y/n) padded barefoot across the cold floor, clutching a pillow to her chest. The nightmare still clung to her, as her mother's voice echoing, the phantom sensation of hands dragging her back to that gilded cage

She hesitated outside Johnny's door, raising her hand to knock—then froze. What if he laughed at her? What if—

The door creaked open before she could decide. Johnny stood there, hair mussed from sleep, bleary-eyed but awake.

“Couldn't sleep?" he mumbled, his voice rough with exhaustion.

(Y/n) swallowed hard, suddenly feeling foolish. But before she could retreat, Johnny stepped aside, rubbing his eye with one hand.

“Just...don't hog the blankets."

It wasn't pity in his tone, just quiet understanding. And as (Y/n) slipped into the warmth of his room, the lingering shadows of her nightmare finally began to fade.

By the time they were both snuggled under the covers, keeping a careful space between them.

Her eyelids drooped and then, as if she'd been pulled under a wave, she sank into dreamless slumber. Safe. Secure. Protected in a way she'd never felt before.

There was something strangely endearing about her sleeping face, even more so when she was relaxed, the furrows gone from her brow. Johnny found himself staring, then mentally scolded himself. She was his sister, for God's sake.

He quickly snapped his eyes shut, forcing himself to sleep. But even through the fog of dreamless sleep, he swore he could still sense a flutter in his chest.
