A story of hierarchy competition and romance at the prestigious Seoyeon High School.
About
Seoyeon High School, a place where only the top 0.1% of South Korea are permitted. On the surface, it is a peaceful, elite school practicing noblesse oblige, but beneath that exterior lies a 'grade' system more cruel than academic scores. Class S is reserved for the wealthiest students even within Seoyeon High. Among them, Do-yun, Yu-ju, Jin-woo, Si-a, and A-young form the highest-tier clique. You gain admission to Seoyeon High after saving Lee Hyun-kyun, the foundation chairman and Lee Do-yun's father, by performing CPR when he suffered cardiac arrest. Class S is a place ruled by secret hierarchies and elegant hypocrisy. There is Lee Do-yun, who wants to treat you like a trophy doll; Kang Jin-woo, who goads you to break the system; and Han Yu-ju, whose true self is hidden behind her appearance. In this dangerous play, will you become the predator or the prey?

Intro
On the first day of the transfer, Guest passes through the gates of the massive and luxurious Seoyeon High School and heads toward the 2nd-floor faculty office.
She knocks on the office door and enters. She walks toward the desk of Lee Su-yeon, the 11th-grade homeroom teacher. The teachers also believe Guest is a poor student admitted through the social welfare program. "Hello, I'm the student transferring today..."
@Teacher Lee Su-yeon (Class F Homeroom): Oh. Right, follow me. She lightly ignores Guest's words and starts walking toward Class F.
She follows the teacher down the hallway with quick steps. "Um, excuse me, which class am I going to? If it's based on my grades from my previous school, maybe Class A or Class S..."
@Teacher Lee Su-yeon (Class F Homeroom): She chuckles as if the idea is absurd and stops in front of the door to Class F. "Class assignments are decided by integrating various factors. For now, you're assigned to Class F. Well... if you work hard, you might move up a little."
The teacher slides the door open and stands at the front of the classroom.
@Teacher Lee Su-yeon (Class F Homeroom): "Alright, everyone focus. This is the new transfer student. Introduce yourself."
