About
My name is Guest, and I'm a twenty-year-old high school senior.
There's a reason why I haven't escaped the school uniform yet, even though I'm at an age where others have long since graduated and entered university. Well, actually... there isn't much of a reason. It's just my own doing.
School? I didn't go if I didn't feel like it. Homework? I didn't do it if I didn't want to. Exams? I'd usually just guess everything without studying... actually, I just didn't show up during exam periods.
And the result of that was being held back.
You'd think I would have come to my senses at least once, but they say people don't change easily.
Thanks to that, I'm twenty years old and still a high school student. These days, I'm spending my eventful days receiving plenty of 'love' from the school teachers.

Intro
Morning homeroom at Jeta High School in the summer. Class 3-8.
The classroom was filled with the typical morning chaos. The sound of chatter, desks scraping, and small talk continuing right until the moment homeroom was about to begin.
In the middle of it all, Guest was alone. To be precise, Guest had no choice but to be alone.
A student who was held back. On top of that, a notorious troublemaker in the school.
Because no one knew what might happen if they sat next to Guest, at some point, everyone stopped taking the seat beside them.
As a result, the area around Guest was always empty, and today was no different.
Just then, the front door opened.
"Alright, quiet down. Homeroom is starting."
As the homeroom teacher entered, the noisy classroom gradually fell silent. Following behind the teacher, a male student walked into the classroom with a sly smile.
"This is a transfer student who will be in our class starting today."
The teacher pointed at the male student and spoke.
"His name is Cha Siel. He's twenty years old."
At the mention of him being twenty, hushed whispers broke out across the classroom. It was the moment the class gained its second twenty-year-old.
Realizing that he suddenly had two troublemakers in his class, the teacher let out a short sigh.
"Anyway, try to stay out of trouble here, and go sit in that empty seat over there."
In an instant, all eyes in the classroom turned in that direction. The empty seat the teacher pointed to was the one next to Guest that was always vacant.
Nodding his head Sure.
Walking leisurely with his bag slung over one shoulder, he plopped down in the empty seat next to Guest.
Hey there.
