The Morning Investigation

Chapter 12: An Early Morning at School

The sun was still low when Aira arrived at school.

The air felt fresh and quiet. Only a few students were walking through the school gate. Aira held her bag tightly and walked slowly.

She felt nervous.

Beside her, Hikari walked with confidence.

“Relax,” Hikari said with a smile. “I’m here.”

Aira nodded.

She trusted Hikari more than anyone.

They entered the school building together.

Chapter 13: Hikari’s Secret Plan

Before class started, students were still chatting.

This was Hikari’s chance.

“Stay here,” Hikari whispered to Aira. “I’ll do the work.”

Aira’s eyes widened.

“O-Okay…” she said quietly.

Hikari walked around the classroom like it was normal. She smiled, joked, and acted casual. But her eyes were sharp.

One by one, she checked the boys’ notebooks.

She waited until no one noticed.

Then -

Click.

She secretly took a picture.

Haruto’s notebook.

Later -

Click.

Yoshi’s notebook.

And later, during a quiet moment -

Click.

Fuyutake’s writing on a student council paper.

Hikari checked her phone.

Mission complete.

Aira watched from her seat, her heart beating fast.

Chapter 14: Breakfast at the School Cafeteria

When the bell rang, Aira and Hikari went to the school cafeteria.

The smell of bread and warm food filled the air.

They sat at a small table near the window.

Aira tried to eat, but her hands were shaking.

“Too nervous to eat?” Hikari teased softly.

Aira nodded.

Just then -

“Hey.”

Haruto stood in front of them.

“Can I join you?” he asked.

Aira’s face turned red.

“Y-Yes,” she said.

Haruto sat down and smiled.

They talked about class and homework.

He laughed gently.

Aira looked at him and felt her heart move.

Hikari watched quietly.

Chapter 15: Yoshi’s Strange Behavior

Across the cafeteria, Yoshi sat with other boys.

But today, he was different.

He was quiet.

No jokes.

No loud voice.

Instead, his eyes kept moving.

Looking at Aira.

Again.

And again.

Aira noticed.

She felt uncomfortable.

“Yoshi is acting strange,” she whispered to Hikari.

Hikari nodded.

“I noticed,” she said.

This made the mystery deeper.

Chapter 16: Fuyutake’s Calm Request

After lunch, student council members gathered.

Fuyutake stood straight, calm as always.

He walked toward Aira.

“Aira,” he said politely.

“Do you have free time after class?”

Aira was surprised.

“I… I think so,” she answered.

“I need help with student council work,” Fuyutake said.

“It won’t take long.”

Aira nodded.

“O-Okay.”

Hikari watched from behind.

Her eyes narrowed slightly.

Chapter 17: A Long School Day Ends

Classes felt longer than usual.

Aira could not focus.

Haruto’s smile.

Yoshi’s quiet eyes.

Fuyutake’s calm voice.

Everything mixed in her head.

Finally, the last bell rang.

Aira and Hikari walked home together.

But today -

Hikari followed Aira home.

“We need to talk,” Hikari said seriously.

Chapter 18: Handwriting on the Screen

Inside Aira’s room, the door was closed.

Hikari sat on the bed and took out her phone.

“I took many pictures,” she said.

Aira sat beside her, nervous.

Hikari placed the phone between them.

One picture.

Two pictures.

Three pictures.

Haruto’s handwriting.

Yoshi’s handwriting.

Fuyutake’s handwriting.

Hikari compared them with the love letter.

Her face became serious.

“These three…” Hikari said slowly,

“are very close.”

Aira gasped softly.

Her face turned red.

“H-Huh…?”

Her heart started to race.

Chapter 19: Aira’s Blushing Silence

Aira covered her face with her hands.

“I can’t look,” she whispered.

Hikari smiled.

“You’re really shy,” she said gently.

Aira nodded.

“My heart feels too loud,” she said.

Hikari lifted her phone again.

“Aira,” she said, smiling,

“stay like this for a moment.”

“W-Why?” Aira asked.

Hikari raised the phone.

Click.

One picture.

Click.

Another picture.

Click.

And another.

Aira sat on her bed, blushing, shy, and confused.

Hikari captured the moment.

Chapter 20: Three Names, One Letter

The room became quiet.

“So,” Hikari said softly,

“Haruto. Yoshi. Fuyutake.”

She looked at Aira.

“One of them wrote the letter.”

Aira’s heart beat hard.

She did not know what to say.

She did not know what to feel.

Outside, the sky slowly changed color.

Chapter 21: To Be Continued…

The answer was close.

But not yet revealed.

A shy girl.

A brave best friend.

Three boys.

One secret letter.

And a red post box that started everything.

END OF PART TWO

Who is the secret admirer?

The answer waits in Part Three…
