Chapter 2: Cigarette Smoke and Secrets

The clatter of plastic containers being tossed into the trash was the only sound for a long moment after Sukuna pushed back from the couch. He stretched, the tendons in his neck cording, and fished a crumpled pack of cigarettes from the pocket of his grease-stained jeans.

“Gonna smoke. Try not to burn the place down while I’m gone,” he said, not specifying which of them he was talking to. The balcony door screeched open on rusty tracks, and he stepped out into the cooling evening, a silhouette against the sodium-glow of the streetlights below.

The silence he left behind was thick, alive with the hum of the refrigerator and the distant, rhythmic thump of bass from a neighbor’s stereo. Mizuki stood rooted by the coffee table, her body stiff. She could feel Megumi’s gaze on her like a physical weight.

She busied herself wiping a smudge of oil from the table’s edge with her thumb. The action was pointless. Everything here was permanently stained.

“He hates being indoors for too long,” Megumi said. Her voice was conversational, soft. “Says it makes him feel caged. I think that’s why he likes the shop. All that open space, all that broken metal he can put back together.” She had shifted, curling one leg beneath her on the couch. The oversized shirt rode up her thigh.

“It’s… a talent,” Mizuki offered, the words hollow.

“Mmm.” Megumi studied her, head tilted. Her dark eyes held a peculiar, dispassionate curiosity, like a child observing an insect. “Can I ask you something? It’s maybe a little personal.”

A cold trickle of unease traced Mizuki’s spine. “Sure.”

“Do you ever feel it? That… absolute wanting?” Megumi’s lips curved, not quite a smile. “Not just, ‘oh, he’s handsome,’ or ‘he’s funny.’ But a need so deep it feels like your bones are hungry for it. Like you’d tear the world apart just to be the only thing he sees.”

Mizuki’s breath hitched. She thought of Sukuna’s rare, gruff compliments, the way he’d sometimes squeeze her hand when he thought she wasn’t looking. It had felt like enough. Now, it felt like crumbs. “That sounds… intense.”

“It is.” Megumi’s gaze drifted to the balcony. Through the grimy glass, they could see the red ember of Sukuna’s cigarette arc through the dark as he gestured, talking to someone on his phone. “He has that effect. He consumes. Most people can’t handle it. They see the tattoos, the yelling, and they run.” She brought her eyes back to Mizuki. “You stayed. I wondered why.”

This was her opening, a chance to connect. “I see past the yelling. I see someone who’s loyal. Protective.”

Megumi’s laugh was a short, airy puff. “Protective. Yes.” She toyed with a thread on the couch cushion. “Did he tell you about our mother?”

The shift was so sudden it left Mizuki disoriented. “He said she wasn’t in the picture. That it was just you two.”

“Just us,” Megumi echoed, nodding slowly. “She left when I was a newborn. Just packed a bag and vanished. Kuna-nii was eleven. He remembers her. I don’t. Not really.” She paused, letting the history hang in the oily air. “He has a type, you know. Women with long, dark hair. Gentle faces. Kind eyes. Good listeners. Teachers, usually. Stable.”

Mizuki’s hand went unconsciously to her own hair. A terrible understanding began to dawn, cold and sickly.

“He looks for her in them,” Megumi continued, her voice dropping to a confidential murmur. “In you. Not consciously, maybe. But he’s trying to fix it. To find the version of her that wouldn’t leave. The one who’d stay and make dinner and ask about his day.” She looked directly at Mizuki, and her expression was almost pitying. “It’s not you he wants. It’s the ghost he thinks you can hold.”

The floor seemed to tilt. The neon sign from the auto-shop across the street blinked, staining the room pulses of red, then blue. All of it—the reluctant dates that always ended back here, his simmering irritation at her normalcy, his inability to say ‘I love you’—snapped into a horrifying, obvious pattern. She wasn’t a girlfriend. She was an audition. A placeholder for a memory.

The balcony door screeched open again. Sukuna shouldered his way back inside, bringing a wave of cold air and the acrid smell of smoke. “Fucking landlord is bitching about the bike parts in the hall again. Like I pay him to be a decorator.”

He collapsed onto the couch, and Megumi moved instantly, fluid as spilled ink. She didn’t return to her spot beside him. She slid directly into his lap, her arms looping around his neck, her face burying against his throat. He didn’t flinch. His hands came up, one settling on the small of her back, the other finding its familiar place in her hair. His fingers began to thread through the dark strands, slow and methodical.

“Cold, nii-chan,” she murmured, her voice muffled against his skin.

“You’re always cold,” he grunted, but he pulled her closer, his chin resting on her head. His red eyes, dulled by the room’s gloom, lifted to Mizuki. “You’re still standing there like a lost puppy. What’s your damage?”

He hadn’t noticed. He hadn’t noticed the devastation on her face, the glassy sheen in her warm brown eyes. He was wrapped around his sister, a closed circuit, and Mizuki was just a blurred shape in the periphery.

The words Megumi had spoken echoed in the hollow of her skull. A need so deep it feels like your bones are hungry for it.

She saw it now, in the complete, unthinking way Sukuna held Megumi. In the way Megumi’s body melted into his, a perfect fit. It was a hunger that had been fed for years. It left no room for anything else.

“No damage,” Mizuki heard herself say. The voice sounded distant, automated. “I should go. Early class tomorrow.”

Sukuna shrugged, a motion that made Megumi sway with him. “Suit yourself. Lock the bottom door on your way out, it sticks.”

No ‘I’ll walk you.’ No ‘call me when you get home.’ Just an instruction about a broken lock.

Megumi shifted in his lap, turning just enough to peer over Sukuna’s shoulder. Her face, half-hidden, was serene. Her eyes met Mizuki’s. There was no triumph there. No malice. Just the quiet, absolute certainty of a fact of nature. The sun rises. The engine turns. He is mine.

Mizuki turned, fumbling for her bag and coat. The walk to the door felt a thousand miles long. Each step was heavy, as if the greasy air had solidified around her legs. She pulled the door open, the frigid hallway a shock.

Behind her, she heard Megumi’s voice, sweet and clear. “Goodnight, Mizuki. Drive safe.”

And Sukuna’s low, rumbling follow-up, already distracted. “Yeah, whatever. Don’t get murdered. It’d be a paperwork nightmare.”

The door swung shut with a final, damp thud, cutting off the sight of them, cutting off the warmth of that terrible, private world. She stood in the bleak, fluorescent-lit hallway, surrounded by the smell of old cooking and mildew. The tears that had been welling finally spilled over, hot and silent, tracing paths through the powder on her cheeks. They weren’t tears of anger anymore. They were the quiet, devastating tears of comprehension.

She was nobody’s substitute mother. She was just a ghost, already fading, in a story that had been written for two long before she ever arrived.
