Chapter 2: Friends
 

The day after the celebratory entrance ceremony,
 
regular classes began, bringing a sobering tone to the students who were still reveling in the extraordinary.
 
The first subject of the day was mathematics,
 
specifically the third period, taught by their homeroom teacher, Mr. Hayama.
 
As classmates diligently solved the crunchy math problems, one student, moved his hands sluggishly, resembling a slow-moving turtle.
 
（I don’t get it.)
 
His name is Saito Minazuki.
 
Saito, known for his cheerful demeanor and curiosity in most things, seemed to have an exception when it came … Read the rest

He’s a child who has grown physically but remains a child at heart. That’s Saito Minazuki.
 
“It seems like love is still too early for the childish Saito.”
 
“Shut up. Just you wait; I’ll definitely have a cute girlfriend and show her off before I graduate high school.”
 
“Sure, sure. I’m not expecting it, but I’ll be waiting.”

Chapter 1: Entrance Ceremony
 

 
As the winter chill began to ease, and the sun rose a bit earlier in the spring,

“Hah, hah, hah, hah.”
 
With large strides, he extended his legs, maintaining a steady rhythm,
 
but today, he was running a bit faster than usual, swiftly navigating the familiar path.
 
“Oh, good morning, Saito-kun.”
 
“Good morning, Grandpa! You seem lively today too.”
 
Arriving at the turning point, he was greeted by a familiar old man.

Prologue
 

 
In this world, there is something called destiny.
 
When, where, with whom you meet, whom you fall in love with, and whom you marry—it’s all predetermined.
 
It’s supposed to be unchangeable from the beginning.
 
However, on a noisy summer day, with the loud chirping of cicadas,
 
On that one summer day, destiny did change.
 

 
It’s a common occurrence in stories, but for her, this was the second time.
 
The trigger was unclear.
 
She simply realized that, in an instant, time had rewound from adulthood back to her childhood.
 
She experienced what is … Read the rest
