The maglev station platform stood high above Mirai Central, offering a breathtaking panorama of New Vein City at night. The sprawling metropolis stretched out beneath them, a tapestry of glittering lights and sleek skyscrapers that pierced the velvet darkness of the night sky. The distant hum of the city's never-ending pulse drifted up to them, a comforting backdrop to their shared moment.

She couldn't stop smiling. Satori's hand remained wrapped around hers as they stood side by side, waiting for her train. The solid warmth of his palm against hers felt so right, so natural, like they'd been holding hands for years instead of mere hours. His thumb occasionally brushed against her skin in small, gentle circles that made her pulse quicken.

"It's beautiful up here," she murmured, breaking the comfortable silence between them. Her voice was soft, almost dreamy. "I always forget how amazing the city looks at night. All those lights, like stars brought down to earth."

Satori squeezed her hand gently. "Most people never look up. They miss half the world that way," he replied, his gaze still fixed on the glittering expanse before them.

His voice sent another wave of warmth cascading through her, from her chest to the tips of her fingers and toes.is voice, the same one that had poured raw emotion into a microphone just an hour ago, was now a low murmur that sent a fresh wave of warmth through her.

Emi stole a glance at his profile, admiring the sharp line of his jaw, the thoughtful set of his dark eyes as he surveyed the cityscape. The station lights cast intriguing shadows across his features, highlighting their newfound strength. How had she never noticed him before? How had she walked past him so many times without seeing what was right in front of her?

How had Natalia never mentioned how incredible her stepbrother was?

The digital display flashed an incoming train alert—three minutes until arrival. Three minutes until their perfect day together had to end.

"So," she said, turning toward him, her blue hair catching the station lights and shimmering with iridescent highlights. She fidgeted slightly, her fingers playing with the edge of her crop top. "What happens now? With us, I mean."

Emi's heart pounded so loudly she was certain he could hear it over the distant rumble of the approaching train. Her reddish-brown eyes searched his face eagerly, hopefully, filled with the unspoken possibilities of what their connection might become.

Satori turned to face her, his expression shifting to something softer, more vulnerable than she'd seen before. He lifted his free hand and gently tucked a strand of her sapphire hair behind her ear, his fingers lingering on the curve of her cheek. The contact sent a wave of warmth through her body that made her knees feel weak, her breath catching in her throat as she unconsciously leaned into his touch.

"Emi," he said, her name a low, gentle rumble from deep in his chest. "I had an amazing time today. Honestly, this was the best part of my week." His dark eyes held hers, completely serious and focused solely on her. "You're incredible. You're bright and funny, and you see the world in a way that makes me want to be better."

Her heart soared at his words, but something in his tone made her breath catch. There was a hesitation there, a weight she couldn't identify.

Satori sighed, his thumb stroked her cheek in a gentle caress that sent shivers down her spine.

"But I have to be honest with you. My life is complicated right now. The entrance exams, family stuff, this new Aspect... I'm not in a place where I can be the boyfriend that a girl like you deserves."

"Oh," she managed, her voice small. She bit her lower lip to keep it from trembling. "Okay. I get it."

The train appeared in the distance, a sleek silver bullet gliding toward them on invisible magnetic fields.

Satori saw her expression and immediately leaned closer, his forehead almost touching hers, his voice dropping to an intimate whisper meant only for her ears.

"Hey. Look at me."

She raised her eyes to meet his, fighting back the sting of tears.

"This isn't a 'no.' It's a 'not yet.'" His eyes searched hers, intense and sincere. "Can you wait for me? Just until after the exams? Until I can get my feet under me?"

The final chime of the train's arrival sounded, the mechanical doors sliding open with a soft whoosh. Other passengers began boarding, paying no attention to the two teenagers locked in their private moment.

"Yeah," she whispered, a slow smile returning to her face. "I can wait."

The train gave its warning chime, signaling the doors would soon close. Satori squeezed her hand one last time before releasing it, taking a step back.

"Get home safe, Keystone," he said, the nickname rolling off his tongue naturally, like a private code between them.

"Keystone?" Emi asked, puzzled by the unfamiliar term.

Satori's mouth curved into a small, private smile. "It's what you are. Someone essential. Someone who holds everything else together."

The words settled around her heart like a warm blanket on a cold night. Emi backed into the train just as the doors began to close, her eyes never leaving his until the last possible moment.

She sank into an empty seat by the window, a sharp ache of having to wait mingling with the soaring joy of his promise. He wanted to be with her. He just needed time.

As the train pulled away from the station, Emi caught a final glimpse of Satori standing on the platform, watching her leave. He raised a hand in farewell, and she pressed her palm against the cool glass in response, even though she knew he probably couldn't see her through the tinted windows.

Today had been one of the best days of her life, a perfect memory she would replay over and over in the nights to come.

Pulling out her phone, Emi's fingers flew across the screen.

I had an amazing time too. And yes. I'll wait. ❤️

She hit send before she could second-guess herself, then clutched the phone to her chest, her heart racing. Almost immediately, three dots appeared, showing he was typing a response. Emi held her breath.

You're worth waiting for too. Sleep well, Emi.

A soft squeal escaped her lips, drawing curious glances from other passengers that she barely noticed. Giddy with happiness, she hugged herself, the emerald green blouse he'd bought her rustling softly against her skin.

The train curved around a bend, offering a panoramic view of the city. Somewhere out there was Satori, heading back to the same condo as Natalia. Emi wondered if she should text her friend about what had happened today, then decided against it. This felt too new, too precious to share just yet. She wanted to hold it close, to savor every moment before letting the rest of the world in.

"Miss? We're at Asahi Central Station."

Emi blinked, startled from her daydream by the train attendant's voice. She hadn't even noticed the train had stopped.

"Oh! Thank you," she said, gathering her shopping bag and hurrying to the doors just before they closed.

The station was less crowded than Mirai Central, filled mostly with workers returning from evening shifts. Emi walked through the familiar neighborhood in a dreamy haze, barely noticing the usual sights and sounds—the fragrant steam from the late-night food stalls, the laughter spilling from the corner izakaya, the holographic advertisements flickering against building facades.

Her phone chimed with a message from her mother asking when she'd be home. Emi quickly typed a response, promising she was just a few minutes away.

As she turned onto her street, reality began to seep back in, bringing with it questions she'd been too happy to consider earlier. Why had Satori asked her to wait? What complications in his life made him unable to be with her now? And why had he called her "Keystone," of all things?

The questions swirled in her mind, but they couldn't diminish the joy of the day. Whatever his reasons, he had been honest with her. He hadn't led her on or made promises he couldn't keep. He'd asked her to wait, and waiting implied something worth waiting for.

Emi paused outside her family's apartment building, looking up at the night sky barely visible through New Vein's protective dome. The stars were faint, outshone by the city lights, but she knew they were there all the same. Some things didn't need to be seen to be believed in.

"I can wait," she whispered to herself. "I can definitely wait."

With that resolve warming her heart, Emi climbed the stairs to her apartment, already counting the days until she would see Satori again.

Inside her family's modest apartment, the familiar scents of cooking oil and spices greeted her. Her mother looked up from the kitchen table where she was calculating the day's receipts, her tired eyes brightening at the sight of her daughter.

"How was your study date?" Hanako asked, taking in Emi's flushed cheeks and bright eyes.

Emi hugged the shopping bag to her chest, a smile blooming across her face that told more than words ever could.

"It was perfect, Mom," she said simply. "Absolutely perfect."
