The scent of spring lingered in the air.
Cherry blossoms fluttered past the classroom windows, painting the sky in soft hues of pink and white. Students chatted excitedly about the new term, their laughter filling the room with life.
But to Haru, the world felt muted.
As though something essential was missing.
He sat by the window, his chin resting on his hand, watching petals drift aimlessly through the breeze.
Once, he would have called days like this meaningless.
Now, he knew better.
Each passing moment felt fragile—precious in a way he had never understood before.
Because she had taught him their worth.
Because she had disappeared.
An Absence Only He Could Feel
"Haru."
Sora's voice broke through his thoughts.
He turned slightly. "Yeah?"
"You've been staring out the window for ten minutes."
"Has it been that long?"
"You didn't even notice when the teacher called your name."
He sighed. "I answered."
"You stood up and said, 'Present,' to the wrong class."
Haru blinked. "Wait… seriously?"
Sora pinched the bridge of her nose. "You're hopeless."
Despite herself, she smiled faintly.
Haru chuckled. "Sorry. My mind's just… somewhere else."
"With her?"
He didn't answer.
He didn't need to.
Sora followed his gaze to the cherry blossoms swaying outside. Her expression softened.
"…You still remember everything, don't you?"
"Every word," he said quietly. "Every smile."
A gentle silence settled between them.
Then Sora spoke again.
"If you keep living in the past, you'll lose the future she protected for you."
Haru smiled faintly.
"I'm not living in the past," he replied. "I'm holding onto a promise."
The Assignment That Changed Everything
The bell rang, signaling the end of the period.
Their homeroom teacher entered the classroom carrying a stack of papers.
"Listen up, everyone," she announced. "To celebrate our school's anniversary, each class will prepare a historical display using old records and yearbooks. You'll work in pairs."
Excited murmurs spread throughout the room.
"Your task is to gather photographs and stories from the past," she continued. "We want to showcase the memories that shaped our school."
Haru felt something stir within him.
Memories.
Fragments.
Echoes.
"Sora," he said quietly.
She raised an eyebrow. "Don't tell me—you're actually interested in a school project?"
"…Let's check the archives."
Her eyes widened slightly.
Then she nodded.
"Alright. But if this turns into another rooftop therapy session, I'm charging you."
The School Archives*
The archives were tucked away behind the library—a quiet, dusty room rarely visited by students.
Sunlight streamed through a narrow window, illuminating rows of aging shelves. The air smelled faintly of paper and time.
Sora brushed dust off a nearby table.
"Wow," she muttered. "This place looks like it hasn't been touched in decades."
Haru scanned the shelves, his fingers trailing along their spines.
Stacks of yearbooks lined the walls, each one containing fragments of forgotten lives.
Laughter.
Friendships.
Dreams.
Memories.
"…It's strange," he murmured.
"What is?"
"These books hold thousands of moments. People who lived, loved, and moved on."
Sora glanced at him. "You're getting philosophical again."
He smiled faintly.
"Maybe. Or maybe I finally understand how valuable memories are."
A Familiar Name
They began searching through the older volumes.
Years passed with every turn of a page.
2015.
2016.
2017.
2018.
Dust gathered on their fingertips as time unraveled before them.
Then—
Haru froze.
"…Wait."
Sora leaned closer. "What is it?"
His hand trembled as he pointed to a photograph taken ten years ago.
A group of elementary students stood beneath a blooming sakura tree during a spring festival. Their smiles were bright, innocent, and filled with hope.
Among them—
A young boy with messy black hair.
Himself.
And beside him—
A girl with long, flowing hair and gentle eyes.
Her smile was soft.
Fragile.
Unforgettable.
Printed beneath the photograph were the students' names.
Kisaragi Haru.
And—
Tachibana Yuki.
The Moment Time Stopped
Sora's breath caught.
"…That's her."
Haru's heart pounded against his chest.
"She was real," he whispered. "She existed."
Fragments of memory surged forward like a breaking dam.
The scent of cherry blossoms.
The laughter of children.
The warmth of spring sunlight.
And a frail girl sitting beneath a sakura tree.
A Promise Beneath the Sakura Tree
"I don't have much time," young Yuki had said, her voice trembling.
"What do you mean?" Haru asked.
She smiled weakly. "I'm sick. The doctors say my heart is fragile."
Haru frowned. "Then you just have to get better!"
She giggled softly. "You're kind."
"No, I'm serious!"
He picked up a fallen cherry blossom and placed it gently in her hands.
"If you can't stay, then I'll give you my days!"
Her eyes widened. "You can't do that."
"I can!" he insisted. "You can borrow my tomorrows!"
She looked at him in surprise.
Then smiled.
"…You're strange, Haru."
He held out his pinky finger.
"Then promise me. If you disappear, you'll come back someday."
After a moment's hesitation, she hooked her pinky with his.
"Okay," she whispered. "It's a promise."
The Memory Returns
The vision shattered.
Haru staggered back, gripping the edge of the table.
"I remember," he gasped. "Everything…"
Sora steadied him. "Haru!"
"That promise… it wasn't just childish nonsense."
He stared at the photograph, his eyes glistening.
"She kept it."
The Truth in Ink
Sora turned the page and froze.
"Haru… look at this."
Below the photograph was a small note printed in fine text:
In Loving Memory of Tachibana Yuki
A gentle soul who brought warmth to everyone she met.
May her smile bloom forever like the cherry blossoms.
Haru's world fell silent.
"…She died," he whispered.
The words felt unreal.
Heavy.
Unbearable.
Yet undeniably true.
Sora's voice trembled. "So Yuki… the one we met…"
"…Is living in the tomorrows I promised her," Haru finished softly.
A Miracle Born from Memory
The room seemed to grow colder.
Dust floated in the still air, illuminated by the fading sunlight.
"So she isn't a ghost," Sora said quietly.
"No."
"…Then what is she?"
Haru closed his eyes.
"A miracle," he replied. "One born from a promise… and sustained by the days I wasted."
Sora stared at the photograph.
"…Then saving her means…"
"Giving up my future," he finished.
Silence fell between them.
The Weight of Tomorrow
Sora clenched her fists.
"I won't let you do that."
Haru looked at her.
"…Sora."
"You can't sacrifice your life for someone who's already gone," she said, her voice trembling. "I won't allow it."
He smiled gently.
"You don't have to worry. I haven't made that decision yet."
"…Yet?"
He turned back to the photograph.
"But now I know the truth."
The setting sun bathed the room in golden light, illuminating Yuki's smiling face.
"And that means I won't run anymore."
A Whisper from the Past
As Haru reached out to touch the image, a sudden breeze swept through the archives.
The pages of the yearbook fluttered.
Petals drifted through the open window.
And for a fleeting moment—
He heard her voice.
Soft.
Gentle.
Familiar.
"You remembered."
His breath caught.
"…Yuki?"
But the room was empty.
Only the photograph remained.
And her smile.
A Promise Renewed
Haru closed the yearbook carefully.
"I'll save you," he whispered. "No matter the cost."
Sora watched him silently.
Then sighed.
"You really are impossible."
He chuckled. "You've known that since we were kids."
She crossed her arms.
"Fine. If you're going to chase miracles, you won't do it alone."
He looked at her in surprise.
"Sora…"
She smiled faintly.
"I'll help you find her."
As they left the archives, cherry blossom petals drifted through the corridor, glowing in the golden light of evening.
Somewhere beyond time and memory—
A girl waited.
And this time—
Haru would not let her disappear.
