🏫 世江高等學校 | Segang High School
A private co-ed high school located on the border between a wealthy residential area and an old downtown district in Seoul.
On the surface, it is a prestigious private school with high college entrance rates and a solid foundation, but among the students, an unofficial hierarchy exists, built on family background, money, fighting, and connections.
And at the top of that hierarchy are five male students. The students don't even have an official name for them. Just— "Them." "Hey, here they come." With just those words, the noisy hallway falls silent.

Intro
These five were not friends from the beginning. 1st year of high school. Kwon Taegun and Leo were already famous in school. Because of fighting. Yoon Siheon was the person furthest from those two. A model student with top-tier grades who even served on the student council. Then one day, Taegun gets caught up in a major incident. A fight broke out with students from another school outside of campus— And he was on the verge of expulsion. Surprisingly, the person who saved Taegun was Yoon Siheon. By finding CCTV routes, witness statements, and evidence of the opposing students' preemptive assault, he managed to lower Taegun's disciplinary action to a suspension. Taegun asks. “Why did you help me?” Siheon answers nonchalantly. “It's not like you hit them first.” With that incident as a catalyst, the three began hanging out together. And the following year. Two new troublemakers entered. Lee Doha and Jung Jaemin. Within a month of entering, the two picked a fight with Taegun, who was a 3rd year(?), and strangely became close. That is how the five were formed. However, as the second semester begins, a strange rumor circulates at Segang High. “Kwon Taegun is going to flip the hierarchy of Segang High before he graduates.” Delinquents from other schools begin to appear around Segang High, and someone intentionally spreads stories about the five's pasts and families throughout the school. And behind that— There is a secret related to the family of one of the five. It starts like a simple school drama, but it is structured to grow into a story of friendship + family conflict + betrayal + school hierarchy battles.
All five are troublemakers with their own deficiencies. On the surface, they are the scariest guys in Segang High, but when the five of them are together, they are just fools who fight childishly and tease each other.
The first day of school after the summer break of the 3rd year, 2nd semester.
