Chapter 4: Storm Shelter
The silence in William’s apartment was a different creature entirely from the tense quiet of the teachers’ lounge or the hollow, waiting stillness of Izuku’s own home. This silence was warm, filled with the faint traffic hum from four stories below and the gentle sigh of the baseboard heaters. Sunlight, pale and wintry, streamed through a large window overlooking a bleak city park, pooling on the warm honey tones of the wooden floor.
Izuku stood just inside the doorway, his single duffel bag hanging from his hand like a dead weight. He wasn’t looking at William, who was hovering awkwardly by the kitchenette, trying to seem nonchalant as he put away groceries. Izuku’s black eyes were sweeping the living room, wide with a kind of shell-shocked awe.
It was, by most standards, a modest space. A low, overstuffed couch upholstered in a faded floral print that had probably been stylish decades ago. Bookshelves bowed under the weight of history texts, biographies, and a surprising number of well-thumbed crime novels. The walls were a gallery of another life: framed photos of a younger William in football gear, mud-streaked and grinning; group shots of laughing men with arms slung around each other’s shoulders at what looked like tailgates or bars. In every one, Shouta Aizawa was a central, magnetic presence—taller, broader, his smile wider and more commanding, his arm often possessive around William’s shoulders. A silent, frozen archive of camaraderie. On the coffee table, amidst scattered newspapers and a forgotten coffee mug, sat a single, unlit pillar candle, its wax solidified into a dripped, waxy stalagmite, a relic of some abandoned evening.
But to Izuku, it was a cathedral of empty space.
His own house was a study in controlled tension, every object placed with rigid precision, every square foot charged with the potential of becoming an obstacle, a provocation. Here, there was room to breathe. To move.
William cleared his throat, the sound too loud. “Make yourself at home, kid. It’s not much, but… well. The couch pulls out. It’s decent.”
Izuku didn’t seem to hear him. He let his duffel bag slide from his fingers. It hit the floor with a soft thump. He took one step forward, then another, into the center of the sunlit patch on the floor. He turned in a slow circle, his head tilted back, his waist-length hair swaying.
“Will,” he said, and his voice was airy, disbelieving.
“Hmm?”
“There’s so much space?”
William paused, a box of pasta in his hand. He blinked. “It’s a one-bedroom apartment, Izuku.”
“No, I mean…” Izuku spread his arms wide, as if to measure the air itself. “Just… space.”
And then, without preamble or performance, he moved.
It wasn’t a casual movement. It was an eruption of pure, trained kinetic energy. He brought his feet together, his posture aligning into a taut, perfect line. One slender arm curved above his head, the other extended out, fingers precise. He was suddenly no longer a slouching, defensive teenager in a baggy sweatshirt. He was a spindle of disciplined grace.
He pushed off from the floor, rising onto the ball of one foot, and spun.
It was a pirouette, but not a wobbly, amateurish turn. It was tight, controlled, a furious whirl where his body became a single, rotating axis. His hair flew out around him like a dark nebula. He didn’t travel; he occupied the same spot, spinning once, twice, three times—a blur of black and faded denim against the honey-colored wood and dusty sunlight.
William froze, the pasta box forgotten. His mind blanked. All he could see was the shocking, beautiful precision of it.
Izuku landed the final turn with a soft, precise click of his shoe, falling into a graceful fourth position, one foot pointed neatly behind the other. He wasn’t even breathing hard. He just stood there, posed, his eyes bright with a fleeting, unguarded triumph.
The silence returned, thicker now.
William slowly set the pasta box on the counter. He walked a few steps into the living room, his eyebrows knitted together. “Jesus, Izuku,” he breathed, his voice low with genuine shock. “Where’d you learn that?”
The moment shattered. Izuku’s pose dissolved. He dropped his arms, slouching back into his familiar, defensive posture, as if suddenly remembering who he was supposed to be. The light in his eyes dimmed, replaced by a wary caution. He shrugged, looking down at his own feet. “Nowhere. Just messing around.”
“That wasn’t messing around,” William said softly. He gestured vaguely at the space where Izuku had just been a spinning top. “That was… professional. You’re a dancer.”
It wasn’t a question. Izuku flinched at the word, as if it were an accusation. He shoved his hands deep into his pockets. “It’s nothing. Just ballet. It’s stupid.”
“Ballet.” William let the word sit in the warm air. He looked at the boy—the petite frame, the slender wrists, the way he carried himself even in his slouch with an inherent, hidden balance. It explained the physical contrast to Shouta, the surprising strength in his narrow shoulders. It explained the discipline, the ability to hold himself so still under verbal fire. It explained nothing at all. “How long?”
Izuku mumbled something at the floor.
“Kid. Look at me. How long?”
Izuku’s head snapped up, a flash of defiance in his eyes. “Since I was six, okay? Nine years. Happy?” The words were a challenge, a dare for William to mock him.
But William just nodded slowly, absorbing it. Nine years. A secret life, running parallel to the one of anger and detention slips. A world Shouta must have known about, must have… what? Approved? Tolerated? Used as another point of control? The questions buzzed in William’s head like wasps.
“Why keep it a secret?” William asked, leaning back against the arm of the couch.
Izuku’s defensiveness curdled into something darker, more brittle. “It’s not a secret. It’s just mine. It’s not for… for people here. They’d just make it into something else. Call me names. Make it ugly.” He kicked lightly at his duffel bag. “You weren’t supposed to see that.”
“I’m glad I did,” William said, and he meant it. It was a piece of the puzzle, a piece of the real Izuku that wasn’t forged in reaction to his father. “It’s incredible. You’re incredible at it.”
Izuku stared at him, searching his face for any hint of sarcasm, of the condescension he was so used to from other men, from teachers, from his father’s friends when they commented on his size, his hair. He found none. Only sincere, bewildered awe.
The tension seeped out of his shoulders, replaced by a shaky exhaustion. The adrenaline of the spin, of the revelation, was fading. He looked suddenly very young, and very tired. “Can I… is there water or something?”
“Of course. God, sorry. Sit down.” William moved quickly to the kitchen, pulling a glass from a cupboard. As he filled it from the tap, he watched Izuku in the reflection of the microwave door. The boy didn’t sit on the couch. He sank to the floor right where he’d been spinning, cross-legged in the sunbeam, tracing a finger along the grain of the wood.
William brought him the water. Izuku took it, gulped half of it down, then cradled the cool glass against his chest.
“He’s gone for three days,” Izuku said to the floor, his voice flat. “A ‘professional development conference.’” He imbued the phrase with a scathing irony that was far too old for him. “Said to find someone to stay with. Didn’t care who.”
William’s gut tightened. He sat on the floor too, keeping a few feet of that precious space between them. “You could have said no to me. Found a friend.”
Izuku barked a short, humorless laugh. “What friends?” He looked up, his eyes meeting William’s. The vulnerability there was a naked, terrifying thing. “You were the only one I knew wouldn’t… ask questions. The wrong ones, anyway.”
William understood. Others would have asked where his dad was, why he couldn’t stay alone, would have wanted to call Shouta to confirm. William just said yes. Because of the damp letter. Because of the empty house. Because of the look in the boy’s eyes in the doorway of the teachers’ lounge.
“I’m glad you asked,” William said simply.
They sat in silence for a long moment. The sunbeam crept slowly across the floor.
“He hates it,” Izuku said suddenly, quietly. “The ballet. Says it’s for weak people. For girls. He only lets me do it because my mother… she signed me up, before she left. He says it’s a useless discipline, that it makes me look…” He trailed off, biting his lip.
“Look how?” William prompted, though he could guess.
“Like her,” Izuku whispered. “Small. And breakable.” He finally took a sip of water. “Sometimes… after, I can’t get my shoes off. My feet are too swollen. Or I’m sore in places I didn’t know I had. He sees me limping. He’ll just smile. Says it’s proof it’s breaking me down, not building me up. Says real strength doesn’t look like that.”
William felt a cold, familiar fury coil in his stomach. He looked at the photos on the wall, at Shouta’s frozen, commanding grin. He remembered the man’s philosophy: strength was dominance, size, vocal power. The absolute opposition to the controlled, silent, agonizing strength of a dancer pushing their body to its artistic limit.
“He’s wrong,” William said, his voice harder than he intended. “What you just did… that takes a kind of strength he’ll never understand. A kind of control. It’s not weakness. It’s a weapon he can’t even see.”
Izuku looked at him, his expression unreadable. He didn’t agree or disagree. He just stored the words away, somewhere safe. “Can I take a shower?” he asked, changing the subject abruptly. “I feel gross.”
“Bathroom’s down the hall. Towels are in the closet. Clean ones.”
Izuku uncoiled himself from the floor, moving with that innate, fluid grace. He retrieved his duffel and disappeared down the short hallway. A moment later, William heard the click of the lock and then the groan of pipes as the water turned on.
William let out a long, shuddering breath he hadn’t realized he’d been holding. He stayed on the floor, the sunlight now warming his legs. Ballet. The pieces snapped together with a cruel logic. The emotional volatility—dancers were tuned instruments, feeling every vibration. The misbehavior—an outlet for the frustration of a passion that was denigrated at home. The defiance—the only form of power he was allowed to express.
The water ran for a long time.
When Izuku emerged, he was transformed again. His hair was damp, darkening the back of a soft
