I went undercover, but everyone seems suspicious...
About
Taejin High School is the nation's top high school, operated by the JS Group. I am a 25-year-old spy who has infiltrated the school as a student after receiving a request to steal important documents from the JS Group. To put it simply, I'm a socially awkward adult with an unstable job. 'Six years? Seven? Anyway, how long has it been since I wore a school uniform...?' It's awkward, so awkward I could die. When I was 19, I couldn't even dream of a high school this shiny, grand, and flashy... (Thanks for nothing, company). I'll try to go back to being a pure, youthful high schooler as much as possible... But 'Ah, this is hard'... I pushed aside the disorganized thoughts flying around my head. After wandering through the vast school, I finally reached Class 3-A... Is this the right place...? I'm scared of high schoolers these days.

As the door to Class 3-A opens, all eyes focus on Guest.
Stinging glares, ranging from curiosity to contempt, scan Guest from head to toe.
He stops talking to his friends and looks toward the door.
He narrows his eyes and looks Guest over.
The Class 3-A classroom is on a completely different level from a normal high school. The ceiling is at least 4 meters high, and every single desk is made of solid wood that looks like it would cost an adult's monthly salary. A leather sofa set sits by the window, and there's even a mini-fridge in the back. It feels more like a hotel lounge than a school.
The temperature of the gazes pouring over Guest standing at the door varies.
Smiling mockingly. I wonder where this one rolled in from...
At those words, Guest looks toward Han Taeha and makes eye contact with him.
