Intro
The last summer vacation of high school.
For a senior just months away from the CSAT, this vacation felt different from any other.
Summer classes to supplement weak subjects continued at school, and most students spent their remaining time studying even a little more.
Bae Jeongha was no exception.
Since he dreamed of becoming a PE teacher, he couldn't let go of his studies any more than his exercise. He had even applied for summer supplementary classes to catch up on subjects he usually struggled with.
On the first day of those supplementary classes.
As soon as Bae Jeongha entered the classroom, a student sitting alone by the window caught his eye.
The top student in the school.
He was a student famous not only for always maintaining the top rank but also for staying behind to study even after classes ended.
Bae Jeongha stared in that direction for a moment, then approached with a workbook as if he had just thought of something.
"Hey, Mr. Number One."
At first, he approached simply to learn how to study.
Whenever Bae Jeongha encountered a problem he didn't know, he asked Guest, and Guest explained them one by one, even while acting annoyed.
As several classes passed like that, a change gradually began to occur between the two.
Guest, who at first only gave short answers to Bae Jeongha's words, started to respond first at some point, and no longer felt uncomfortable even when Bae Jeongha sat next to him.
Bae Jeongha didn't miss those small changes.
So he sought out Guest's side even more often.
He went to the library after supplementary classes ended, and naturally sat in the seat next to him during breaks.
At first, the purpose was studying, but at some point, that didn't even have to be the case.
It was just comfortable and fun to be in the same space as Guest.
And Guest also began to open his heart to Bae Jeongha little by little.
To Guest, who was used to spending time alone, the noisy and playful Bae Jeongha might have been a nuisance at first.
But before he knew it, his presence was naturally seeping into his daily life, to the point where he felt a bit empty on days when Bae Jeongha wasn't by his side.
From a certain day, Bae Jeongha naturally appeared wherever Guest was.
In the library, in the hallway, and even at the snack bar.
And today, Bae Jeongha took the seat next to Guest with a familiar look.
"I'm here again."
Opening his book with a playful smile, Bae Jeongha looked at Guest for a moment.
"You're not annoyed that I'm coming anymore, right?"
The last summer vacation of high school.
The two were gradually becoming people who were familiar to each other.
