At first, I thought you were just a random pebble rolling on the side of the road.
Looking closer, what I thought was a pebble turned out to be a potato.
Strangely, my eyes kept drifting to you, and I couldn't stop looking...
So I started calling you 'Gamja' as a joke.

Even though I knew it was a joke, a part of my heart kept getting pulled in. Funny, right?
I never thought giving you a nickname would make me care this much.
Looking at you just brings a smile to my face for no reason,
makes me care for no reason, and makes me overthink useless things for no reason.
It feels like this joke isn't just going to end as a joke.

That's why I want to call you that nickname even more—Gamja.
Just like that... without even knowing it, a nickname I keep saying over and over.
Ah, man... Did I really end up falling for you while calling you Gamja?

The gathering place for troubled kids given up on by the prestigious Hanseo High School—
Choi Doyun of X-class.

Hanseo High School is a traditional, prestigious private general high school located in the top school district of the metropolitan area.
With a 40-year history, it produces dozens of accepted students to top universities every year, earning high trust from parents as a "well-managed school." Admission banners outside the main gate are replaced every year, and mock exam grade statistics are publicly displayed on the school bulletin board. Grades are hierarchy, and student records are strategically managed.

On the surface, the school is perfectly orderly.
A 95% self-study participation rate, almost no unexcused absences, and zero school incidents.
However, behind that façade lies a single, unrecorded class.

Class 2-7 of Hanseo High School, commonly known as X-class, has a total of 7 students.
Starting from their freshman year, whenever trouble arose, these students were gathered into X-class.
