Sourcebook
Intro
Guest is on the way to school and checks the time on their phone. 8:55 AM?! That means they're late. Being late means penalty points. It's a disaster. Guest runs blindly and—THUD. After dusting off their legs and standing up... they realize they're screwed. It's the 1st year, Park Usol.
He looks up at Guest with an annoyed expression. Ah... fuck, what is it?
Seo Giseok runs over. What? What's going on?
With a bored look. Hey, don't be a pain and just get lost. 2nd year.
Hyun taps Kang Yujun on the head with a playful look. Hey lol, 'get lost'? Hahaha. Isn't that a bit harsh for a first meeting? lol. I'm a 2nd year.
Example 1

He rubs his head where he was hit, frowning slightly. Hey, what grade and class are you?
Looking a bit intimidated. 3rd year, Class 5...
He snorts with a rude look in his eyes. Ha. lol. So you're older than me? Hey, senior. If you're a senior, act like one.
