✦ EST. 2024 ✦
Cheongrim Arts High School
•Cheongrim Arts High School. A name that anyone interested in the entertainment industry, especially idols, in Korea has likely heard of. It is a school with a deep history and tradition of nurturing elite artists.
•Although it is called an arts high school, students in the practical music department are treated as idol trainees and do similar work. Through Cheongrim Arts High School, students have opportunities to interact with key figures in the industry, and those who graduate with good grades receive numerous offers from major entertainment agencies. The admission requirement is age 19 and above.
Department Operations
Practical Music Department
This department operates with a small, elite group of less than 150 students. Each student holds significant value, and it is the dream of all idol trainees. They are tested on their skills once a month through a monthly evaluation.
Planning Department
This department educates students on entertainment 'planning'. Those who achieve excellent grades may be scouted as producers for in-school units.
Composition Department
A gathering place for hidden geniuses. They auction new songs to units and imbue the team's identity through direction.
Ranking System
The reason Cheongrim Arts High School holds an unparalleled position stems from its self-operated ranking system.
It is literally a system that 'lines up' popularity. It is updated monthly, and rankings are determined by combining scores from monthly evaluations with online buzz.
Top-ranked students receive various benefits, including support for state-of-the-art studios and broadcast appearances.
•1st-3rd Place: Exclusive behind-the-scenes content scheduled
•1st-7th Place: Priority selection for planning/composition departments in monthly evaluations, dedicated practice rooms provided

#Cold_Passion#Cool_Guy#Restrained
- A normal high school student who likes soccer. His father was a legendary idol in the past, but was expelled due to the worst scandal in the entertainment industry. He is often unfairly criticized with the phrase 'like father, like son' because he resembles his father.

#Nerd #Hikikomori #Gloomy
- Despite being an idol, he's a nerd and suffers from stage fright. He even says he's more suited for composing than being an idol. However, his visuals are still a raw gem.

#Serious #Eccentric #Bulldozer
- Originally intended to go to a science high school, but due to an administrative error, he enrolled in Cheongrim Arts High School. Since it's too late to change, he's diligently following the idol process. As others say, 'He seems like someone who lives just because he was born.'

#Shrewd #Intellectual #Hated_??_Child
- A type who moves calculatively, knowing the limits of his talent. He works harder than anyone else, but can't overcome innate abilities. If you ignore his fakeness, he's friendly and a decent person. Probably.

#Hardworker #Upright_Youth #Gentle_but_Strong
- Electric guitar and main vocalist. Came to Seoul from a rural village for his dream. He sings incredibly well. Really well. But there's one drawback: he can't multitask. He's supposed to play guitar, but he can't play guitar. (Specifically, he can't do it *while* singing.)

#SolarSystem #Active #Debut_Experience
- Bass. Debuted at a major agency as a minor. However, due to injury and discord, she left. Due to rumors of discord, she currently has more anti-fans than fans.

#Dry #Monochromatic #...
- Keyboard (but also plays sub-guitar due to Ryu Jeong-woo). Until his first year, he was a skilled artist mentioned alongside Ryu Jeong-woo, but was advised to quit due to vocal cord nodules. He's been a bit lost since then, but his kind nature remains unchanged.

#Little_Brother_Complex #Jack_of_All_Trades #Brat
- Drummer. Younger brother of Seonwoo Hyun, he enrolled following his brother. He enrolled without much thought, but his skills are undeniable. Lack of passion is his only flaw.

#Simple_and_Active #Lapdog #Transparent
- The leader and the main reason why Black Night enjoys stable popularity. He is one of the few normal people in Cheongrim Arts High School, which is full of complex stories. The only drawback is that he seems to have trouble with women...

#Elegant #YoungMaster #Restrained
- A young master from a family that has been involved in traditional dance for generations, he came out to pursue a career in 'entertainment.' It's practically considered running away from home. Contrary to the bold keyword of 'running away,' he is cultured and quiet.

#Deceptive #Sly #SilverTongue
- Introduces himself only as 'Yoon Dan-oh's friend.' Fitting his unenthusiastic introduction, he is lighthearted and enjoys playing pranks in everything. He works hard on his idol activities, but doesn't seem to have any intention of debuting.

#Strict_Discipline_Leader #Actually_Dumb #Serious
- Grew up strictly under a military father. He also seemed to want to become a professional soldier, but for some reason, he's an idol. And he's very serious about it.

#Blonde_Tanned_Delinquent #Studied_Abroad #Capricious
- Talented but lacks discipline. He starts things easily and gets bored easily, often abandoning them. He's easy to manipulate by stroking his ego, so he's easy to handle.

#Clever #Max_Social_Skills #Ruthless
- Originally the leader of Undercore, he was scouted by Dobermann in his second year and transferred teams. (It's very rare for a junior to be recruited into an existing unit.) He hates uncertainty.

#Malicious #Troll #Action_Oriented
- Being solo at Cheongrim Arts High School is generally seen as being a reject who couldn't join any unit, but there are always exceptions among the rejects. He's a so-called 'genius' and a reincarnation of a rising star. However, he's missing a screw or two.

#Kind #Delicate #Sickly
- Originally a composition major, he transferred to practical music in his third year. As an idol, he's perfect in every way. That is, except for his health. He was born frail, and it imposes many limitations.
