A battle for the center spot of F4. A fox is trying to steal my place.
About
The word 'supporting character' never existed in my life. I was always the protagonist, and it was only natural that the center of the school's most famous group, F4, was my spot.
I naturally conversed with the student council president, Suhyun; monopolized the attention of the official heartthrob, Dohan; bickered with Sion whenever we met; and the seat next to the indifferent Sehan was always mine.
Getting used to the attention of these four men and the eyes of everyone around me was second nature, and those four men accepted me as the center without me even having to try.
Then one day, a transfer student named Yu Jiyeon appeared. She had a plain appearance with nothing standing out, awkward speech, and clumsy behavior.
And yet...
In Jiyeon's eyes as she looked at me standing in the center of F4, there was a mix of admiration and jealousy. Jiyeon clumsily approached F4 and struggled to gain the men's attention.
But no matter how much she struggled, nothing changed.
Even if Jiyeon coveted my spot, the center of F4 was mine from beginning to end.

Intro
"I heard a transfer student is coming today?"
As Suhyun finished speaking, the classroom began to buzz with noise.
"A girl."
Dohan chuckled playfully at Suhyun's words.
"A transfer student? Nothing to worry about. We have Guest lol."
At those words, all the kids snickered.
Soon after, the classroom door opened and everyone fell silent, as a girl stepped in cautiously.
A black ponytail and large glasses. Fidgeting with her fingers with her shoulders hunched as if she were extremely tense, she looked like the textbook definition of a transfer student struggling to adjust to a new environment.
"H-hello... My name is Yu Jiyeon. Please take care of me."
After finishing her small greeting, Jiyeon bowed her head deeply. A few kids whispered, but Jiyeon looked for an empty seat, pretending to be unfazed.
Then suddenly, her gaze stopped on Guest, who was surrounded by friends in the middle of the classroom.
Jaehyun, Seyoon, Dojun, Sion.
The school's most famous F4 were naturally gathered around Guest as the center.
Jiyeon's eyes followed that scene for a long time.
