The fever struck with the sudden, deceptive ferocity typical of late April chills.
A sudden coastal squall had caught Shiori two blocks from the university station on Tuesday afternoon. Though she had sprinted beneath the awnings, her shoes and wool cardigan had been thoroughly soaked by the icy sea wind. By seven that evening, as she sat at the low table attempting to read a chapter on classical rhetoric, her eyelids had grown heavy and hot, and a relentless, bone-deep ache had settled into her joints.
"Shiori?" Ren called from the kitchen counter, where he was peeling potatoes for dinner. "Is the apartment cold? You are shivering."
"I am fine," Shiori murmured, pulling her cardigan tighter around her shoulders. Her voice was uncharacteristically hoarse, rasping like dry paper. "Just... a little tired from the seminar."
Ren set down the peeler immediately.
He crossed the tatami floor in three strides and knelt beside her cushion. Without a word, he reached out and pressed the back of his hand flat against her forehead.
The skin beneath his fingers was burning.
"Shiori, you are on fire," Ren said, his voice tightening with immediate, protective concern.
"It is only a slight chill," she protested weakly, though even lifting her head made the room tilt in nauseating waves. "You have your structural analysis critique tomorrow morning at nine. You cannot get sick because of me. Go finish your presentation."
Ren didn't argue. He simply leaned forward, slipped one arm beneath her knees and the other behind her shoulders, and lifted her smoothly into his arms.
"Ren!" she gasped, her burning cheeks turning scarlet from embarrassment. "Put me down! I can walk!"
"Hush," Ren whispered gently, carrying her into the tatami bedroom.
He laid her down on the thick futon, which was already spread with the soft cream duvet. He reached for the digital thermometer on the bedside shelf, waited for the green light to blink, and gently slid the cool plastic tip beneath her arm.
Thirty seconds later, the device let out a series of high-pitched chirps.
Ren looked at the liquid-crystal display.
38.7°C.
His jaw set in a quiet, immovable line. He pulled the heavy duvet up to her chin, tucking the edges securely around her shoulders.
"Rest," he commanded softly, brushing the damp bangs away from her flushed forehead. "Do not move. I am taking care of everything."

For the next four hours, Apartment 402 became a quiet, focused infirmary.
First, Ren called his studio project partner, Miura, explaining that a family medical emergency would prevent him from attending the preliminary morning session, though he had already uploaded the digital blueprint renderings to the shared cloud drive. Then, he changed into a clean cotton t-shirt, tied his hair back with a small rubber band, and went into the kitchen.
In a porcelain basin, he mixed cold water with two ice cubes. He brought a folded linen hand towel to the bedroom, wrung it out until it was damp and cool, and laid it gently across Shiori's burning forehead.
A soft, shuddering sigh of relief escaped her lips as the cold fabric touched her fevered skin.
"Better?" he asked, kneeling beside her pillow.
"So cold," she whispered, her eyes fluttering open, glistening with feverish glassiness. "It feels so good, Ren."
Kohaku, sensing that something was wrong with his favorite human, trotted into the bedroom on silent white paws. He jumped onto the edge of the futon, circled twice, and curled himself into a dense, warm crescent directly over Shiori's cold, wool-socked feet, purring with a low, steady rumble that acted like a soothing anchor against the chills racking her frame.
"Good boy, Kohaku," Ren murmured, scratching the cat behind his notched ear. "Keep her feet warm."
Ren returned to the kitchen.
To nurse a fever, there was only one proper medicine in a traditional Japanese home: tamago zousui, the gentle egg-and-rice porridge that warmed the stomach without taxing a weakened body.
Ren placed a clay donabe pot on the small gas burner. Into the pot, he poured four cups of clear dashi broth simmered from kombu seaweed and dried bonito flakes, adding half a teaspoon of light soy sauce and a pinch of sea salt. When the broth began to simmer gently, sending up a rich, fragrant steam that smelled of the ocean and autumn forests, he added two cups of cooked white rice that he had rinsed in cold water to remove the surface starch, ensuring the porridge would be light and silken rather than heavy.
He finely diced half a sweet carrot, letting the tiny orange cubes soften in the broth until they were as tender as butter.
Finally, in a small ceramic bowl, he beat two fresh farm eggs with a pair of cooking chopsticks until the whites and yolks were blended into liquid gold. Holding the bowl high above the simmering pot, he drizzled the eggs into the broth in slow, concentric ribbons, letting the steam cook the egg into delicate, fluffy yellow clouds that floated across the surface of the rice.
He finished the porridge with a sprinkle of finely minced green scallions.
The aroma that drifted through the apartment was simple, pure, and overwhelmingly comforting: the essence of domestic care distilled into a single pot.

Ren carried the steaming porridge into the bedroom on a wooden tray, accompanied by a small porcelain spoon, a ceramic mug of warm roasted barley tea, and a dish of mild pickled daikon.
He set the tray on the low floor table, knelt beside Shiori's futon, and gently lifted her shoulders, propping two thick pillows behind her back so she could sit upright.
"You need to eat a little," Ren said, lifting the lid of the clay pot. A cloud of fragrant steam rose between them, carrying the rich scent of egg and dashi. "Even if it is just three spoonfuls. You need energy to fight the fever."
Shiori looked at the steaming bowl. Her throat felt raw and parched, but the sight of the golden egg clouds and the tender rice made her stomach stir with faint, grateful hunger.
She reached out to take the porcelain spoon, but her hand was trembling so violently from the fever that the ceramic clattered against the tray.
"I will hold it," Ren said softly.
He dipped the porcelain spoon into the porridge, gathering a small mound of rice, carrot, and fluffy egg. He brought the spoon to his lips, blowing on it gently until the fierce steam subsided to a safe, soothing warmth.
"Open," he said.
Shiori looked into his brown eyes, which were filled with such pure, unhurried devotion that a sudden tightness gripped her chest. She parted her lips, letting him guide the spoon into her mouth.
The porridge was magnificent.
The dashi was savory and deep, the rice melted against her tongue without any effort of chewing, and the egg was as soft as morning silk. As the warmth slid down her raw throat and settled into her cold stomach, a wave of comfort washed through her entire body, loosening the tight knots in her aching muscles.
"It is so delicious, Ren," she whispered, her voice cracking slightly.
"Then have another," he said patiently, blowing on a second spoonful.
He fed her seven spoonfuls in total, pausing whenever she needed to sip the warm barley tea, watching her with the patient, vigilant care of a mother tending a fragile child.
When she finally shook her head, unable to eat more, Ren set the bowl aside, wiped the corner of her lips with a clean napkin, and helped her slide back down beneath the heavy duvet. He replaced the warmed towel on her forehead with a fresh, cold one from the basin.
Shiori turned her face on the pillow, watching him as he sat cross-legged on the tatami beside her mattress.
"Ren," she murmured, her eyelids drooping with heavy exhaustion.
"I am here."
"When I was little," she whispered, her voice small and muffled by the blanket, "whenever I got sick, my mother would be so stressed. She was always working at the clinic, and my father was always at the office. I learned very early to stay completely quiet under the blanket. I didn't want to cough because I was afraid of making them angry. I thought that being sick meant I was an inconvenience to the people around me."
Tears, hot and heavy from the fever, slipped from the corners of her eyes, soaking into the white cotton of the pillowcase.
Ren's heart ached with a sudden, fierce tenderness.
He reached out, his long, warm fingers gently wiping the tears from her temple. Then he slid his hand down, taking her small, burning hand in his, closing his fingers securely around hers.
"Listen to me, Shiori," Ren said, his voice deep, low, and vibrating with absolute truth. "You are not an inconvenience. You could never be an inconvenience to me. Taking care of you is not a chore. It is the greatest honor of my life. Whenever you are sick, whenever you are tired, whenever you cannot walk on your own... I will carry you. I will cook for you. I will sit beside your bed until the fever breaks. That is what we promised on the bench."
Shiori pressed her cheek against his arm, her breathing slowing as the relief seeped into the deepest corners of her soul.
"You really won't leave?" she whispered.
"Never," Ren said, leaning down to press a soft, warm kiss against her burning forehead, just below the cool edge of the towel. "Go to sleep, Shiori. I will be right here when you wake up."

The fever broke at five in the morning.
Outside the balcony glass, the coastal dawn was rising in clean, pale washes of gold and lavender. The sea was calm, reflecting the morning light like a mirror of polished silver.
Shiori opened her eyes.
The heavy, oppressive heat that had weighed down her chest was gone, replaced by a light, cool sensation of restored health. Her skin was damp with broken sweat, but her joints no longer ached, and her breath was cool and clear.
She turned her head slowly on the pillow.
Ren was still there.
He had not returned to his own futon during the night. He was sitting on the floorboards beside her mattress, his upper body slumped forward, his forehead resting against the edge of the tatami mat beside her pillow. He was sound asleep, his breathing deep and exhausted, his hair falling messily over his eyes.
And even in sleep, his right hand was still closed tightly around hers, their fingers interlaced on the edge of the cream duvet.
At the foot of the bed, Kohaku opened one golden eye, let out a tiny, contented squeak, and stretched his white paws before curling back into his sleep.
Shiori looked at Ren's sleeping face, at the faint dark circles under his eyes, and at the gentle strength of the hand holding hers.
Slowly, carefully, she lifted her free left hand and gently touched his cheek, her fingers tracing the warm, familiar line of his jaw.
A radiant, tearful smile touched her lips in the quiet morning light.
*I am not lonely anymore,* she thought, closing her eyes as the morning sun warmed the room. *I will never be lonely again.*
