AN: I've had this done for a while but forgot to post it, oops. And I used Lillia because I unfortunately couldn't find a good picture of Fosca.
You’ve never seen Fosca so steady on her feet.
Her steps are slow, careful, as always—but not for her sake this time. She’s balancing a teacup in one hand and a folded napkin in the other, her thin wrists taut with the effort of not spilling a single drop. She looks almost regal in the firelight, pale and composed in her nightgown and shawl, her hair coming loose from its braid like soft little ribbons of ink.
Normally, she’s the one half-reclined on the settee while you flutter around her. Reading aloud. Brushing her hair. Warming broth in the little iron pot. You’ve been doing that since the first week she let you into her rooms, into her life—just after your eighteenth birthday. It had taken her months to let you do even that.
But now you’re the one buried in her bed, too warm beneath the covers, your throat dry and sore, your skin aching under the weight of your own body. Fosca sets the teacup down on the bedside table with a kind of delicate pride, like she’s accomplished something monumental.
“I stirred it with a bit of honey,” she says softly. “And a pinch of salt. That’s how my aunt used to make it when I was little.”
You try to sit up, but the bed shifts beneath you and your arms don’t quite want to help. Fosca is there in an instant—one hand braced behind your back, the other guiding the cup to your mouth with almost sacred care.
“Slowly,” she murmurs. “There’s no rush.” The tea is too warm, too sweet. But you drink it anyway, because she’s watching you with those feverish, earnest eyes like you’re the only real thing in the world.
“Why’re you—up?” Your voice is hoarse and small. She hushes you gently, brushing damp hair away from your forehead. “I’m not made of glass, darling. You know that.”
You let out a small huff of breath, too tired to argue. You’ve always known she wasn’t made of glass—but there’s something about seeing her upright, determined, hands steady and voice clear, that stirs something deep in your chest. Something younger than you want to admit.
She sets the cup aside and carefully climbs into bed behind you, her thin body curling around yours like an extra blanket. You can feel her fingers tracing slow shapes on your back, just under the hem of your nightshirt.
“You always look after me,” she whispers, more to herself than to you. “I know you’re so young, and it should be the other way around. But I got so used to the way you fuss. The way you tuck the covers around my legs like you’re afraid I’ll float away.”
You hum sleepily, trying to turn toward her. But Fosca’s already pulling you in, pressing your head against her chest. “Well,” she sighs, her voice warm against your hair, “now it’s my turn.”
✧･ﾟ: *✧･ﾟ:* ✧･ﾟ: *✧･ﾟ:*
Fosca doesn’t sleep. She rarely does.
You’ve learned this in the quiet hours, the way you’ve learned every rhythm of her life. Her nights are long and restless, filled with books she never finishes and pages of half-written letters she’ll never send. You’ve watched her lie still for hours, eyes open, breath shallow, as if she’s waiting for something—or someone—that never arrives.
But now, she lies beside you like she’s anchored here.
You’re half-draped across her chest, fevered skin against the thin cotton of her nightgown, your breath soft and shallow against her collarbone. She can feel the heat radiating from you. She worries over it. Of course she does. But beneath that—beneath the furrow in her brow and the way she keeps checking your pulse with her fingertips—there’s something else.
Something that feels like peace.
Her hand moves slowly down your spine. Not lustful. Not even affectionate in the usual way. Just present. Like she’s grounding herself with the shape of you. With the miracle of being allowed to hold something warm and soft and real again.
You shift in your sleep. Murmur her name. She still isn’t used to that. Hearing it from your mouth with no cruelty attached. No scorn. No pity. Just softness. Just need.
Fosca.
She closes her eyes. She had thought Ludovic was her only chance. That love, for her, would always mean pain—stole money and sour longings, humiliation paraded in public. She’d lived in that story so long she forgot there could be another kind.
And then you came. Barely grown, all light and intention, and you chose her. Even now, curled up and sweating through her bedsheets, your fingers twitch toward her in your sleep like you miss her, even in dreaming.
It undoes her. Every time. She presses her lips to your hairline, careful not to wake you. “You make me happy,” she whispers, her voice trembling. “I never thought I’d be happy again.”
You’ve grown quieter now. That’s the first thing Fosca notices. You’re never loud, never unruly, but you’re rarely this… silent. Your breaths come shallow. Your cheeks burn with fever. You sleep more than you wake. And Fosca is unraveling.
Not in panic—she won’t allow herself that—but in a tight, trembling way that sits just behind her ribs. She keeps wiping your forehead with a damp cloth, keeps smoothing your hair back, keeps pressing little half‑kisses to your temple like they might coax you back to her.
“Open your eyes, my love,” she whispers, thumb brushing your cheek. “Just for a moment. Just so I know you’re still here.”
You stir, barely. Your lashes flutter. You make the smallest sound, something like a sigh. Her breath catches anyway. Relief floods her face. She props you up carefully, her thin arms working far harder than they should. She’s winded by the time she gets the cup to your lips, but she doesn’t complain. She’d lift mountains if she had to.
“Drink, darling. Yes, just like that.” Your throat works slowly. She feels each swallow as if it’s happening in her own body.
When you drift off again, collapsing gently against her shoulder, Fosca holds you upright, guiding your head to rest just beneath her jaw. You’re burning. She can feel the heat even through the layers of cloth.
Something twists inside her—fear, fragile but sharp. She never lets it reach her face where you might see it. “I am not going to lose you,” she murmurs into your hair. “I will not. I refuse.”
Her hand trembles as she takes a fresh cloth from the bowl of water she heated minutes ago. She presses it to your forehead, turning it over just before the heat can slip away.
“I’m doing all I can,” she tells you softly, as if you can hear. “I promise you, my darling girl, I am doing everything.”
Her voice cracks—only a little, only once—and she steadies herself almost immediately. She smooths the blanket around you, tucks it under your legs the way you always do for her. She sits on the edge of the bed and leans over you, her breath brushing your cheek.
“You are strong,” she says. “But if you cannot be, then I will be strong for both of us.” Her lips ghost across your forehead—a kiss, a vow, a plea.
“Stay with me. Stay.” A long pause. “I’ve only just learned happiness again, darling… don’t take it away.”
She curls around you then, thin arms wrapping gently around your waist, cheek tucked against your shoulder. Her body is weak, but her hold is steady. She watches your breathing until hers finally matches it.
It’s just after dawn when she realizes she can’t do this alone.
You’re worse. Not just fevered now, but slipping—your skin clammy and pale, your breathing shallow enough that she keeps checking your pulse over and over, terrified she’s only imagining the flutter of it.
She sits beside you for nearly an hour, trying to will you back to her with whispered words, with kisses to your fingers, with cool cloth after cool cloth. But nothing helps. You don’t even stir when she says your name now.
And that’s what undoes her. Not the helplessness. Not even the fear. It’s the quiet. You’ve never been loud, no. But your presence is always felt. The way you hum softly while folding linens. The way you whisper I love you like it’s a spell meant only for her. The way you sigh in your sleep, reaching for her even when you dream.
Now—nothing.
Fosca wipes her eyes quickly, viciously, as if furious with herself for crying. She presses one last kiss to your brow, and stands.
It takes her nearly ten minutes to wrap her shawl around her shoulders, to pull on boots with trembling fingers. Her body aches—her heart more so—but she leaves anyway.
The wind claws at her shawl as she makes her way across the courtyard, breath coming in short, sharp bursts. She should not be out of doors.
The soldiers glance up from their morning drills, startled to see the Colonel’s cousin out of her rooms—walking, no less, with a strange urgency. Her hair is unbraided. Her boots half-laced. There’s no governess trailing her, no servant steadying her steps. She moves like a woman possessed.
And she is. The fever’s barely touched you, and yet it’s undone everything. Fosca’s voice is raw by the time she reaches the infirmary. She doesn't knock. “Doctor Tambouri.”
He looks up, surprised. She hasn’t left her rooms in weeks. Not since Christmas. “My dear—are you unwell?” he asks automatically. She ignores the question. “There’s a girl. She’s fallen ill. High fever, chills, delirium.”
“A girl?” His brow furrows. “Who?” Silence. Fosca is breathing hard now, her hand clutched to the doorframe to steady herself. Her face pale as salt. Her mouth set in a sharp, unwavering line.
“She’s no one,” she says. And then, quieter: “She’s mine.” The doctor stares at her a beat too long. But she doesn’t explain. Not to him. Not to anyone. He reaches for his coat and bag. “Lead the way.”
When they arrive at her rooms—sparse, high-ceilinged, tucked in a crumbling corner of the fort—the fire has nearly gone out. The room smells of sweat and lavender water and fevered skin.
You’re still in her bed. Small. Quiet. Barely breathing. “She’s young,” the doctor mutters, checking your pulse. “Too young to be here with you. Too young to be this ill.”
Fosca turns her head, lips trembling. “Can you save her or not?” He softens. “I can try.” He leaves a satchel of medicines. Compresses. Orders for broth. He says he’ll return tomorrow, maybe sooner.
Fosca doesn’t hear him leave. Her focus is only you. When the door closes, she collapses into the bedside chair, cold fingers curling into the folds of your nightdress.
She leans forward and presses her mouth to your hand, kisses each knuckle like a rosary. “I would die for you,” she whispers. “But I would rather live with you.”
The whispers begin before the doctor even leaves her rooms. A girl—young, unknown, and fevered—discovered half-naked in Signorina Fosca’s bed, in her linens, with her scent on her skin.
By midday, the entire garrison knows. By sundown, even the Colonel refuses to meet Fosca’s eye.
She keeps to her quarters, of course. She always has. But now the silence outside her door has a different weight. It's not respect. It's revulsion. Like her presence is a sickness that might spread.
She hears them outside sometimes—soldiers delivering firewood or fresh cloths, voices lowered in contempt:
“That poor creature… what sort of woman keeps a child like that?” “She must be madder than we thought.” “Disgraceful. She should be sent home.” “I’d rather serve under fire than walk into that room.”
Fosca does not respond.
She wipes your brow with lavender water and honey. She changes your linens when they become too damp with sweat. She reads to you in the evenings from a worn novel you once claimed was your favorite, even though you’ve never stayed awake long enough to hear a full chapter.
She does not defend herself. Not to them. Because she has nothing to prove to anyone who would dare suggest you are anything less than holy.
The doctor returns on the third day. She nearly throws him out. “You brought this upon yourself,” he says, frowning as he checks your temperature. “You know what they say. That you’re keeping her like a Roman whore.”
Fosca’s eyes flash. “Get out.”
He ignores her. “What happens if she dies? You think they’ll weep for you? You think they’ll bury her beside you? No. They’ll send you back to Milan in disgrace, and toss her in an unmarked grave.”
She moves before he can finish. Thin and trembling, but full of fury. “You will not speak of her that way. She is not a mistake. She is not a scandal. She is mine.”
The doctor watches her, something unreadable in his expression. “Love,” he says, “isn’t enough to survive on.” Fosca stares at him. “I have survived on far less.”
That night, she holds you tighter than she ever has before. The fever hasn’t broken. Your body is limp, fragile in her arms, barely more than breath and warmth.
She rests her cheek against your temple and murmurs something soft in Italian, over and over, like a prayer. Something her mother used to say when she was small and sick with winter fevers.
They can say what they want. They can banish her. They can call you shameful, perverse, unholy. But if you live—when you live—she’ll never let go of you again.
✧･ﾟ: *✧･ﾟ:* ✧･ﾟ: *✧･ﾟ:*
The first cool breath you take feels like a miracle.
You wake in the late afternoon, the light warm and low through the shuttered window, shadows long across Fosca’s blankets. Your body still aches, but the burning is gone. The terrible, suffocating heat. The delirium. The drifting in and out of nothingness.
Gone.
Fosca notices before you even open your eyes. She’s been watching you for hours, barely blinking. “Cara?” Her voice cracks. “Are you—can you hear me?”
You blink once. Slow. Heavy. Her hand flies to your cheek and she gasps softly. “You’re cool. Dio… grazie…”
She bows her head against your shoulder, breath shaking like she might weep from relief but refuses to let herself. Not yet. Not in front of you. You rasp, voice faint, “I want—”
“Yes.” She cuts you off, too eager, too desperate to grant anything you ask. “Anything. Tell me.” You swallow, eyes fluttering. “A walk.” She draws back, startled. “A walk?” She repeats it like she’s not sure she’s heard right. “Now?”
You nod. It’s small, barely a gesture, but it’s the strongest motion you’ve made in days. Fosca looks at your face—still tired, still pale—and something determined flickers in her dark eyes. “Then we walk.”
It takes time to dress you. Your legs are unsteady. The air is cold. But Fosca’s hands are gentle and sure as she wraps a shawl around your shoulders, ties your bonnet beneath your chin, and lets you lean fully against her as she guides you to the door.
She shouldn’t be walking either. She’s trembling from the effort. But she won’t let you see that. She won’t let anyone stop you.
When the door opens, the corridor feels enormous, the stone walls colder than you remember. But the air is clean. Fresh. And you breathe it greedily.
The soldiers stop what they’re doing. Every single one.
Conversations cut off midway. Boots still in motion go silent. The courtyard freezes the moment you and Fosca step out into the open—your arm looped through hers, your fingers clutching her sleeve like a lifeline.
The scandal no longer whispered about, but walking in full view.
A kept girl. A sickly woman. A pair.
Fosca lifts her chin. She dares any of them to speak.
You lean into her, dizzy but smiling faintly, and she tightens her grasp on your hand. Her body is small beside yours, fragile, but somehow she holds you upright, guiding you slow step by slow step across the courtyard stones.
The whispers begin again, but quieter than before. Still, you hear them. And Fosca hears them. She turns her head just enough to look at you—not them—her voice low, firm.
“Let them stare,” she murmurs. “They cannot hurt us.” You press closer, your cheek brushing her shoulder. “I don’t care,” you whisper. Her breath catches at that. Not because of shame. But because you mean it. Because you’re alive enough to mean it.
She straightens, pride lifting her spine, and continues walking with you—past the stares, past the judgment, past all the men who never believed she was capable of loving anything.
Her hand trembles, but she holds you like you’re the treasure she smuggled back from death itself. When you reach the far end of the courtyard, Fosca pauses, letting you breathe in the cool wind.
Your fingers squeeze hers. And Fosca smiles—small, soft, astonished. “You came back to me,” she whispers. You don’t have the strength to answer. So you rest your head on her shoulder, letting the whole fort see exactly who you belong to.
✧･ﾟ: *✧･ﾟ:* ✧･ﾟ: *✧･ﾟ:*
They never really noticed you before.
You were a maid. A girl with a mop and a pail and hands too soft for the work assigned to them. You arrived just after the autumn rains, barely eighteen, your skirt hem already fraying, your eyes too wide for a fort this grim. The other women muttered that you were too delicate, too slow. That you'd never last the winter.
The officers didn’t bother to learn your name. Why would they? You served their meals and scrubbed their floors. You carried linens down the long stone corridors and fetched the doctor’s bitter tinctures. They passed you in the halls the way they passed window drafts—something cold and unremarkable.
It was only Fosca who saw you. Really saw you.
Not as a servant. Not as a girl to be dismissed or pitied. But as something quiet and precious. She watched the way you lit the fire in her room without complaint, how your hands lingered just slightly when brushing dust from her bedside table. She asked questions no one had bothered to ask. Had you eaten? Were your shoes warm enough? Did anyone ever call you beautiful?
You started spending more time in her rooms. No one noticed. Why would they? You were just a girl bringing water.
But somewhere between polishing her mirror and folding her letters, she kissed you for the first time. Somewhere between winter and spring, she fell in love with you.
And even then, the fort didn’t notice.
They didn’t see how she began eating again, just a little. How her eyes lit up when you read aloud from her favorite books, stumbling shyly through the pages while she watched you like you were sunlight on marble. They didn’t see the way you brushed out her hair at night, or how she would cup your face with both hands as if the shape of it might heal her.
To them, you were still just a maid. Until the fever. Until the doctor was summoned at dawn, and the whole courtyard heard her voice—I need help. The girl is sick. The girl is mine.
And suddenly, you weren’t invisible anymore.
Now, when you walk through the courtyard, they all look. Not because you demand attention—but because the Signorina walks beside you, her arm tight around your waist, your fingers threaded with hers like something sacred.
You’re not in uniform anymore.
You wear a pale blue dress now, soft cotton, a little loose at the shoulders. Fosca had it made for you the week after your fever broke, too weak to hold the needle herself, but strong enough to order it sewn. You wear her shawl. Her gloves. You smell like her perfumes, subtle and clove-sweet.
The soldiers stare like they’ve seen a ghost turned into a girl. They remember the little maid who once swept their halls. And they don’t know what to make of her now.
Fosca notices the way your shoulders draw in when the whispers start. She tightens her grip on your hand.
“They don’t matter,” she says softly. “They never did.” You glance at her—worn, pale, still trembling with illness but alive—and smile. “They notice me now.”
Fosca’s eyes darken. “Yes. Because they thought they might lose you.” You pause by the fountain. The stone’s still cold, but the first hints of spring are in the air. “And you?” you ask, half teasing, half breathless. “Is that why you saw me?”
She looks at you like you’ve asked if the sun was something she only noticed after it rose. “No,” she says, and her voice doesn’t waver. “I saw you the moment you touched my bedframe and didn’t look afraid.”
She leans in—slow, aching—and kisses your cheek in full view of every man in the garrison. You burn brighter than you ever did with fever.
Let them stare. Let them try to make sense of it. You were never meant to be theirs. Never meant to be invisible. You were always hers. And now, the whole fort knows it.

Parma countryside, 1871
The hens are already squawking by the time you make it down the hill, barefoot and drowsy in your cotton shift.
The sun hasn’t quite cleared the ridge yet. The fields are still silver with dew, the sky a soft wash of blue and honey. You shield your eyes with one hand, the other trailing along the stone wall as you pass the olive trees. Fosca planted those herself, two springs ago. You had warned her she didn’t have the strength for it—but she’d laughed. Told you she had strength enough now for anything.
And she does.
She’s in the garden when you reach the bottom of the hill, crouched beside the tomatoes in her boots and house dress, her sleeves rolled up, hair pinned back. She looks up when she hears your footsteps and smiles in that soft, private way she only ever used with you. The one that still makes your stomach flutter, even after all these years.
“Good morning, wife,” she says, brushing soil from her palms. “Come kiss me. I’ve been patient long enough.”
You laugh—quiet, still sleepy—and crouch beside her in the rows. She smells like earth and rosemary and warm linen. You press your lips to hers, slow and familiar.
“Good morning,” you murmur against her cheek. She cups your face, thumb sweeping lightly under your eye. “Did you sleep well?” You nod, leaning into her touch. “I dreamed of this.” Fosca tilts her head. “This moment?”
“This life.”
The farm isn’t large, but it’s yours. The house is old—sun-baked stone and ivy-climbed walls—but sturdy. Fosca tends the garden. You keep bees. There’s a goat you both pretend to hate and a cat who thinks he owns the place. Some days you rise before dawn. Some days you lie in bed until noon, her hand curled around yours beneath the blankets.
Fosca’s health isn’t perfect. It never will be. But she’s strong now. Stronger than anyone ever thought she’d live to be. Her eyes are clearer. Her hair streaked with silver. She walks with you every morning, and reads aloud every night, and still, every day, she calls you wife with reverence.
Not out of possession. But out of joy. You’re weeding beside her when you hear the carriage roll past on the distant road. Travelers, maybe. Or returning soldiers.
You glance up without thinking, then freeze as you catch the way one of the riders looks toward the farm—stares, just for a moment, before the horse rounds the bend.
You wonder if they recognize her. If they see the Fosca from the fort. The ghost. The woman no one thought would survive, let alone love.
But you don’t ask. You don’t need to. Because Fosca turns to you, fingers brushing yours in the dirt, and smiles with something slow and full in her eyes.
“We’re due at Signora Bianchi’s for bread,” she says. “But she can wait. I’d rather stay here with you.” You lean over and kiss her again. And let the rest of the world keep wondering.
