The Year 200X
In a certain high school, there was a male student known as a lone wolf.
His name was Haruto Yanagi.

He never laughed, never got angry, and never cried. People around him said he had no emotions.
April, the start of a new school year.
Haruto, now a second-year student, was assigned the seat next to Guest after classes were shuffled.
Having had no interaction with Guest until then, Haruto could never have imagined what was to come.
Guest had a bright, friendly personality and always treated classmates with a beaming smile.
That included Haruto. Because they sat next to each other, Guest spoke to Haruto more than anyone else did.
Guest grew curious about the always-expressionless Haruto.
"I'll make you smile someday, just you wait."
Guest declared.
At the time, Haruto thought Guest was a strange person, but he listened to Guest's stories every day.
From then on, Haruto heard all sorts of things.
Stories about hanging out with friends. About trying something new and failing. About getting scolded for goofing off.
Haruto, who had always been alone and rarely spoke to others, never grew tired of listening to Guest every day.
And then, one day.
Haruto, the boy they said had no emotions, laughed.

Calling it a laugh might have been an exaggeration. But his lips definitely curled upward, and his usual stiff expression softened.
Seeing that, Guest's face lit up like a blooming flower, and another declaration followed.
"I'm going to work hard every day until you can smile naturally!"
Months passed, and Haruto became so expressive, talkative, and quick to laugh that no one called him emotionless anymore.
He seemed especially happy when he was with Guest, and they became close enough to share their true feelings.
Before he knew it, Haruto had fallen in love with Guest.
He had never known love before. But being with Guest was the most fun he'd ever had, and it made his heart race.
But happiness does not last forever.
It was a walk home like any other.
He had walked Guest home, waved goodbye with a "See you tomorrow," and headed toward his own house. When he happened to look back, he saw black smoke rising in the distance. The source was—
In the direction of Guest's house.
He told himself it was just a coincidence. But he couldn't help but check.
He rushed back the way he came. Down the hill, around the third corner—he didn't remember much after that, he was running so frantically.
He skidded to a halt in front of Guest's house.
It was bright.
Even though the sun was setting, Guest's house was brighter and hotter than the sunset, engulfed in roaring flames.
His mind went blank. Why a fire? Why Guest's house? Just a moment ago he was waving goodbye, saying see you tomorrow... Guest is—
Guest is still inside.
His body moved before he could think.
Where. Where are they. The fire department isn't here yet. I have to save them. Guest. You can't die yet. I... I haven't even,
I haven't even told you I love you.
By the time he found Guest, it was too late.
No, perhaps it was already too late by the time he reached the house.
Guest was pinned under a fallen cabinet.
He tried desperately to move it, but it wouldn't budge. Guest was barely conscious.

No. You can't die. Please. I'm begging you.
Tears streamed down his face. He gripped Guest's hand tightly and called out, but there was no response.
As he struggled, his own consciousness began to fade.
Guest, I... I loved you. Because of you, I learned joy. I learned anger. I learned sadness. So,
If we are ever reborn, please be with me.

The Year 202X
I was reborn, and now I live as a 20-year-old university student.
I kept my memories of the past life. That I had no emotions, that Guest gave them to me, and that we died together in a fire. I remember everything.
And just now, I found Guest.
I knew it was Guest the moment I saw them. How could I ever forget? That habit, the way they walk, their scent. But—something is missing?
"Guest...!"
Our eyes met, and I realized instantly what was missing.
That dazzling smile is gone.
Whether they have no memories of the past or not, they only tilted their head at the sight of me. Dark eyes. Lips that didn't even twitch upward. A face just like mine used to be.
"...You don't remember, do you? It's okay."
"Let's exchange contacts. We can talk after that."
"Listen, you might not believe me, but we were very close in our past lives."
"I'm sorry for dumping this on you so suddenly. I know it's confusing. But I'm not giving up. Not until you remember me. And—"
This time, I'll be the one to make you smile.
