The sound of the wind and the occasional crackling of charcoal in the fireplace disappeared, leaving only the sound of each other's breath.
Seraphilia blinked in the darkness, seemingly trying to see through it and discern Robin's expression.
A few seconds later, she sat up, not asking why or pretending to refuse, simply and almost obediently saying, 'Okay.'
She picked up her felt blanket and shawl and walked to the bed.
The bed was small, and both of them had to lie on their sides to fit. They lay back to back, with a narrow, awkward gap between them like a boundary.
The initial stiffness and tension almost froze the air. Seraphilia could clearly feel the tension in Robin's body behind her, and she herself was the same, every muscle unable to relax.
This was the first time they had been so close, close enough to feel each other's slight body heat, to hear each other's clear, differently paced heartbeats and breaths.
In the end, it was their bodies' instincts that overcame their conscious guard. The cold was the best adhesive. In her sleep, Seraphilia unconsciously moved closer to the only, faint source of heat. Robin, in her daze, also felt the low body temperature from Seraphilia behind her, and the faint, cool scent from her hair that seemed to have been soaked in ice and snow all day.
That night, they huddled together in the cold, their backs touching slightly through their clothes and blankets.
There was no embrace, no words, just a closeness forced by the severe cold.
But that small shared warmth was like a tiny spark, thrown into the cold, solid barrier between them, making a small 'hiss.'
The next morning, they both woke up almost simultaneously, then quickly moved apart as if shocked. They each got up and started the new day as if nothing had happened.
But something in the air seemed different. A subtle, indescribable tension grew silently in the silence.
Sharing a bed became the norm to fight the cold.
The initial stiffness gradually wore away with bodily fatigue and cold, and their sleeping positions went from stiffly back to back to naturally facing each other slightly, knees occasionally touching lightly when turning over, arms unconsciously seeking warmer spots.
The physical closeness did not dispel Robin's doubts but instead provided her with an unprecedented opportunity to observe closely.
Her probing shifted from observing external behaviors to more private, subtle details.
Seraphilia slept deeply, especially after nights of intense training, in a state of near-unconsciousness.
Robin sometimes pretended to be asleep but opened her eyes in the darkness, greedily examining Seraphilia's sleeping face in the faint light from the window.
She saw that even in sleep, Seraphilia's brows were often slightly furrowed, as if thinking or enduring something. Her lashes were long, casting a faint shadow under her eyes. Her face was always pale, only showing some warmth in the firelight. Her lips were thin, always pursed, revealing a resolve and...a loneliness that Robin found unfamiliar.
Robin's gaze carefully scanned Seraphilia's exposed skin. She saw the small, new and old scratches, alarming frostbite, and some faint bruises in odd places.
What caught her attention most was the skin visible just below Seraphilia's collarbone, at the edge of her collar.
There seemed to be traces of an old scar, but the light was too dim to see clearly.
Robin noted all these details carefully and calmly, like collecting specimens.
Someone so strict with herself, with various training scars, possessing peculiar abilities yet desperately hiding them, of unknown origin yet overly 'kind' to herself...the mysteries grew like a snowball.
One late night, Robin decided to conduct a more active probe.
She waited until Seraphilia's breath became long and even, clearly in deep sleep, before quietly activating her ability.
In the shadow by Seraphilia's pillow, an extremely small, blue flower that blended with the shadow silently bloomed like a silent ghost.
In her palm, an even smaller, almost invisible 'eye' slowly opened.
This was Robin's new, refined use of the Flower-Flower Fruit ability—the 'Prying Blossom,' for extremely close, absolutely hidden observation.
The flower's 'gaze' carefully traced Seraphilia's sleeping face, brushing over the fatigue under her eyes, the corners of her tightly pursed lips, the delicate line of her neck...then, extremely slowly, like the most cautious thief, it tried to peer under Seraphilia's slightly open collar, targeting that suspicious old scar.
Just as that intangible 'gaze' was about to touch the skin at the edge of her collar, about to glimpse that secret—
Seraphilia's long lashes fluttered slightly.
Robin's heart suddenly jumped, as if gripped by an invisible hand!
She instantly withdrew her ability, and the hand prying into the secret dissipated silently in the shadow.
She closed her eyes tightly, held her breath, and stiffly pretended to be asleep, her heart pounding as if it would burst from her chest.
Seraphilia did not move, as if it was just an unconscious movement in her sleep.
But it was a long time, so long that Robin thought she would suffocate, before she heard Seraphilia's breath become even and steady again.
Did she notice?
Or did she not?
Robin was unsure.
But this failed probe made her feel a pang of fear and...a hint of guilt that even she wanted to deny.
The next day, Seraphilia acted as usual.
At breakfast, she even carefully moved the only intact fried egg in the pan to Robin's bowl with a fork. She said nothing, her ice-blue eyes calm, as if the small energy fluctuation by her pillow last night was just an illusion.
Robin ate the egg, the taste the same as always, but she found it hard to swallow.
Seraphilia's silence and this nonchalant act seemed like a silent tolerance, making Robin's probing seem clumsy, childish, and glaring.
A few more days passed, and on an exceptionally cold morning, Seraphilia washed her face with cold water and was about to go out for training. Robin stopped her.
'Wait.' Robin took out a small cloth bag from under the bed, containing some low-quality frostbite ointment and a roll of fairly clean cloth strips she had bought secretly at the grocery store with the money Seraphilia had given her earlier.
'Hand.'
She was concise.
Seraphilia looked at the fresh frostbite and cracks on her fingers, hesitated, then held out her hand.
Robin, with somewhat awkward but extremely careful movements, applied the ointment for her.
The cold ointment touched the wound, causing a sting. During the process, her warm fingertips occasionally touched Seraphilia's cold hand.
'Be careful...during training.' After bandaging, Robin said softly, never looking up at Seraphilia's eyes.
Seraphilia looked at her carefully bandaged, somewhat clumsy fingers, then at Robin's bowed head, revealing soft hair whorls. Deep in those ice-blue eyes, something hard melted slightly.
She softly said, 'Mm.'
After that, Robin never used her ability to pry into Seraphilia's sleep again.
Her probing shifted from active, invasive observation to passive analysis through daily interactions.
She still had doubts, but something had changed—perhaps a more complex understanding, realizing that behind Seraphilia's silent giving, there might be something heavy and incomprehensible.
And Seraphilia knew all this.
She tolerated Robin's vigilance, endured her probing, just as she endured the pain of training and the cold of Black Iron Town.
Because she knew that for the current Robin, trust was not a gift easily given but a fortress that needed to be confirmed step by step, built by her own hands.
All she could do was be the silent, resilient foundation of that fortress, and...the real warmth that could be leaned on in this cold night.
Outside the window, the winter of the West Blue was still harsh, with wind and snow raging. But the two people in the small house found a new, fragile yet resilient balance in the cold and probing.
The destructive ice core silently brewed in Seraphilia's hands, and the seed of trust was quietly planted in the warmth between their backs, waiting for the day it would break through the ice.
