The Department of Business Administration's 'Iron Wall Four'—the department revolves around them.
About
A Word Before You Begin
"Hello, I'm the creator, Doro-dororong. This plot is a remake of 'Cooling Inside,' which was my most-chatted plot before my previous account, DSD, was deleted."
"Actually, except for the Business Department setting, the characters' personalities and backgrounds are all different."
"The reason I'm releasing this plot with semi-realistic visuals is that, though it may be shameless, I wanted to find the confidence that I can achieve good results with an 'enemies-to-lovers' theme once again."
"To be honest, due to the current model situation, 'enemies-to-lovers' scenarios are quite difficult and challenging. Therefore, I recommend using Koji or Luca."
"Since the difficulty is set to Hard, even if it feels like Extreme or higher due to model issues, I would appreciate it if you could refer to the private setting guide I posted on the feed while playing."
"Thank you always for playing my plots."
Background Description
Guest is a freshman in their second semester at Doro University's Department of Business Administration. Having successfully adjusted to the department as a new student, Guest was leading a model freshman life, getting along well with other students and attending university diligently.
In the same freshman class, there were four girls known as the 'Iron Wall Four.' They had received everyone's attention since admission due to their stunning looks, but they ruthlessly shut down any interest from men.
It seemed as if the entire department revolved around them. Despite being targets of countless men's advances and many women's jealousy, the four of them lived their own lives separately, each with a different attitude toward college life. Nevertheless, they became such a hot topic that it was difficult to join any conversation among students without mentioning them.
And so, the second semester of freshman year arrives. The story of Guest and the Iron Wall Four begins.

Sourcebook
Intro
Freshman year, second semester. The first day of classes.
Guest was on their way to attend a morning lecture.
Ugh, a 9 AM class is seriously brutal...
While yawning, they spot a familiar silhouette.
Huh?
She walks on without paying any attention to her surroundings, passing by Guest without a single glance.
'...Was that Han Seoyeon? She's as pretty as ever, but she really doesn't care about anyone around her.'
As they continue walking toward their elective lecture, they turn their head and lock eyes with someone surrounded by a group of girls.
