The storm arrived without warning.
By late afternoon, Tokyo's winter sky had turned almost black.
Clouds gathered above the city in thick layers, swallowing the last traces of sunlight. The weather forecast had predicted heavy rain, but the intensity of the approaching storm surprised even the observatory staff.
Inside the National Astronomical Research Center, researchers hurried to secure equipment and review the evening observation schedule.
Haruto stood beside the main observation terminal, staring through the large windows.
Rain began striking the glass.
At first, softly.
Then harder.
Within minutes, the city below disappeared behind a curtain of water.
Dr. Sakamoto entered the room.
"We're suspending tonight's outdoor observations."
Haruto looked away from the window.
"Because of the storm?"
"Obviously."
Haruto glanced toward the observatory dome.
"We were supposed to collect another set of measurements tonight."
"We'll collect them later."
"But the orbital model—"
"Can wait."
Haruto sighed.
Dr. Sakamoto gave him a knowing look.
"You've been working on this every night for nearly two weeks."
Haruto smiled faintly.
"I know."
"You need sleep."
"I know."
"And food."
"I ate."
"When?"
Haruto paused.
Dr. Sakamoto shook his head.
"Go home."
Haruto looked toward the storm again.
"I'll leave soon."
"That's what you said yesterday."
The older astronomer walked away.
Haruto remained at the terminal.
The latest data from the mysterious star was still displayed on the screen.
The possible orbit.
The periodic brightness variation.
The faint radial velocity signal.
Everything seemed to be pointing toward the existence of an unseen planetary companion.
But they still needed more observations.
He looked at the storm.
Perhaps tomorrow.
Across Tokyo, Aiko stood inside her studio.
The rain was now pounding against the windows.
Thunder rolled across the city.
She had been painting for several hours.
Her latest canvas stood in front of her.
The work was still unnamed.
Dark shades dominated the composition.
But unlike The Silent Painting, this one contained movement.
A storm.
A city.
Two distant windows illuminated against the darkness.
Aiko had begun the painting that afternoon after thinking about Reina's assignment.
Paint something about the person you are becoming.
She wasn't sure what the painting meant yet.
But she knew it felt honest.
Lightning flashed outside.
Aiko stepped away from the window.
The storm reminded her of childhood.
She remembered one particular night.
She had been afraid of thunder.
Haruto had sat beside her and counted the seconds between lightning and thunder to distract her.
She had asked him why he wasn't afraid.
He had answered with the confidence only a child could possess.
"Because the sky can't hurt us if we understand it."
Aiko smiled at the memory.
Haruto had always tried to understand things.
Stars.
Storms.
Dreams.
People.
Perhaps that was why he had become an astronomer.
Her phone vibrated.
She looked at the screen.
No message.
She frowned.
Haruto usually sent something by this time.
She glanced at the clock.
10:42 p.m.
"He's probably still working."
She returned to the painting.
Then the lights went out.
Aiko froze.
The studio became completely dark.
Thunder shook the windows.
She reached for her phone and turned on the flashlight.
"Great."
She checked the building's hallway.
The entire floor was dark.
A power outage.
Aiko walked carefully toward the window.
The city had become strangely dim.
Only emergency lights and distant headlights remained visible.
She looked at her phone again.
One bar of signal.
She hesitated.
Then she called Haruto.
At the observatory, Haruto's phone began vibrating across the desk.
He looked down.
Aiko.
He answered immediately.
"Hello?"
For several seconds, he heard only static.
Then her voice.
"Haruto?"
"Yes."
"Are you still at the observatory?"
"Yes. Why?"
"The power went out at my studio."
Haruto sat upright.
"Are you okay?"
"I'm fine."
"Are you alone?"
"Yes."
He looked toward the windows.
The storm was getting worse.
"Stay inside."
"I am."
"Don't go outside until the weather improves."
Aiko laughed softly.
"I know."
Another thunderclap sounded through her phone.
Haruto heard her go quiet.
"You okay?"
"Yes."
A pause.
"I'm just..."
She stopped.
"Just what?"
"Nothing."
Haruto knew her too well.
"You don't like storms."
"I don't mind them."
"You absolutely mind them."
Aiko smiled despite herself.
"Maybe a little."
Haruto leaned back in his chair.
"Do you remember when we were children?"
"About the thunder?"
"Yes."
"You counted between lightning and thunder."
"That's right."
"You said the sky couldn't hurt us if we understood it."
Haruto laughed.
"I said that?"
"You did."
"I was very wise."
"You were six."
"Exactly."
Aiko laughed.
For a moment, the storm outside seemed less frightening.
Then the call crackled.
"Haruto?"
"I'm here."
"I can't hear you very well."
"I'm still here."
The connection became unstable.
Aiko's voice broke through the static.
"Haruto..."
"Yes?"
"I'm glad I called."
He smiled.
"Me too."
Another burst of static.
Then silence.
The call disconnected.
Haruto stared at the screen.
He immediately called back.
No answer.
Again.
Nothing.
He checked the weather alert.
A severe storm warning had been issued across Tokyo.
His expression changed.
Aiko stood in the dark studio.
She looked at her phone.
No signal.
She walked toward the window.
Rainwater streamed down the glass.
Another lightning flash illuminated the room.
For a moment, she could see her unfinished painting.
The storm on the canvas seemed almost alive.
She remembered Haruto's voice.
I'm still here.
Aiko smiled.
Then another thunderclap shook the building.
She closed her eyes.
"It's okay."
She whispered the words to herself.
But something felt different.
Not fear.
Loneliness.
She had become so used to Haruto being only a phone call away that the sudden silence felt strange.
She sat on the floor beside the window.
Her phone remained in her hand.
She waited.
At the observatory, Haruto couldn't concentrate.
He tried calling again.
Nothing.
He checked the network outage map.
Several parts of Tokyo were experiencing disruptions.
He knew there was probably nothing seriously wrong.
Still, his mind refused to settle.
Dr. Sakamoto returned to the room.
"You haven't left."
Haruto looked up.
"Aiko's power went out."
"Is she safe?"
"She said she was."
"Then trust her."
Haruto nodded.
But he couldn't stop looking at his phone.
Dr. Sakamoto studied him.
"You've been staring at that screen for five minutes."
"I know."
"Go home."
Haruto looked surprised.
"What?"
"You've done enough work tonight."
"But—"
"No."
Dr. Sakamoto pointed toward the door.
"Go."
Haruto finally stood.
He packed his laptop.
Before leaving, he looked at the observation screen one last time.
The star remained there.
The data remained incomplete.
The mystery remained unsolved.
But for once, that didn't bother him.
There were things more important than research.
The journey home was difficult.
Several train lines had delays because of the storm.
Haruto eventually got off at a station several blocks from his apartment and walked through the rain.
His umbrella struggled against the wind.
Water soaked the edges of his coat.
His phone remained silent.
He tried calling Aiko again.
Nothing.
When he finally reached his apartment, he immediately checked the weather reports.
The storm was expected to continue for several more hours.
Haruto sat down.
He stared at his phone.
Then he remembered something.
Aiko's studio had emergency lighting.
She had told him about it months ago.
She would be fine.
He repeated that thought several times.
But he still couldn't relax.
At 1:17 a.m., Aiko's phone finally vibrated.
She looked down.
Haruto:Are you okay?
She smiled.
Aiko:Yes.
A second message arrived.
Haruto:Power back?
Aiko:Not yet.
Haruto:Stay inside.
Aiko:I am.
She hesitated before typing another message.
Aiko:Were you worried?
The typing indicator appeared.
Then disappeared.
Then appeared again.
Finally:
Haruto:A little.
Aiko smiled.
Aiko:Only a little?
Haruto:Fine. A lot.
She laughed quietly.
The storm continued outside.
But somehow the studio no longer felt as lonely.
She sent him a photograph.
The unfinished painting.
Haruto opened it.
He stared at the image.
Dark clouds.
Rain.
Two glowing windows.
He recognized something immediately.
"That's us."
He typed:
Haruto:I like it.
Aiko:It's not finished.
Haruto:Neither are we.
Aiko stared at the message.
Her expression softened.
She typed:
Aiko:That's true.
They remained on the phone for nearly an hour.
Sometimes they talked.
Sometimes they said nothing.
Aiko worked on her painting.
Haruto sat by his apartment window watching the storm.
At one point, Aiko asked,
"What do you think you'll discover?"
Haruto knew exactly what she meant.
"The planet?"
"Yes."
He thought about it.
"I don't know."
"Are you excited?"
"Very."
"Scared?"
"A little."
"Why?"
"Because if we're right, everything changes."
Aiko smiled.
"That's what you always wanted."
"Yes."
She looked toward her painting.
"Change is scary."
Haruto nodded.
"But sometimes it's necessary."
Aiko smiled.
"Reina says something similar."
"She's a good mentor."
"She is."
A quiet moment passed.
Then Aiko asked,
"Do you ever miss university?"
Haruto thought about it.
"Sometimes."
"The observatory isn't the same."
"No."
"Do you miss being a student?"
He smiled.
"I miss having fewer responsibilities."
Aiko laughed.
"Me too."
"But I don't want to go backward."
Aiko looked at the storm outside.
"Neither do I."
They both became quiet.
Growing up had once seemed like something that happened automatically.
Now they understood that it was something they had to consciously accept.
Their lives were changing.
Their careers were becoming more demanding.
Their dreams were taking them into unfamiliar places.
And sometimes, those changes would frighten them.
But they didn't have to face them alone.
At 3:04 a.m., the storm finally began to weaken.
The rain became softer.
The wind slowed.
Aiko stood near the window.
"Haruto."
"Hm?"
"Look outside."
He walked to his own window.
"The storm is ending."
Aiko smiled.
"Maybe the sky is tired."
Haruto laughed.
"Maybe."
A few seconds passed.
Then Aiko said,
"Good night."
"Good night."
Neither ended the call immediately.
Finally, Aiko whispered,
"Thank you for staying."
Haruto smiled.
"Always."
The call ended.
Morning arrived quietly.
The clouds began to separate.
Sunlight touched the wet streets.
Puddles reflected the pale sky.
Aiko stood inside her studio.
The power had returned.
She turned on the lights.
Then she looked at her painting.
Something had changed.
Not the painting.
Her understanding of it.
The storm was no longer simply a storm.
It was a memory.
A reminder.
Sometimes darkness arrived without warning.
Sometimes the people we loved couldn't physically be beside us.
Sometimes all we could offer each other was a voice through a telephone connection.
But sometimes that was enough.
Aiko picked up her brush.
She added one final element to the painting.
A small light in one of the distant windows.
Then she stepped back.
She smiled.
Across Tokyo, Haruto returned to the observatory.
The storm had cleared the atmosphere.
The sky was unusually transparent.
Dr. Sakamoto stood near the telescope.
"Good morning."
"Good morning."
"You look exhausted."
"I am."
Dr. Sakamoto pointed toward the telescope.
"But you're lucky."
Haruto looked up.
"The sky is clear."
A faint smile appeared on his face.
Perhaps the storm had taken away their observation opportunity the previous night.
But the morning had given them something else.
A clean sky.
A fresh beginning.
Haruto prepared the telescope.
The mysterious star appeared on the monitor.
The data collection began again.
He watched the first measurement appear.
Then the second.
Then the third.
The signal was still there.
The mystery remained.
But now Haruto felt calm.
He knew some discoveries took years.
Some took decades.
And some answers came only after the storm had passed.
He looked through the observatory window toward the brightening sky.
Somewhere across Tokyo, Aiko was probably looking at the same morning.
Two people.
Two dreams.
Two different worlds.
Still connected beneath the same sky.
Haruto smiled.
Then he returned to his work.
The search continued.
To be continued...
