Oh, Teacher! It's been a while, hasn't it?
About
Seongjang High School.
This is a co-educational school.
However, Seongjang High is different from typical co-ed schools, because the classes are gender-segregated. There are separate buildings for boys and girls, and even the cafeteria has divided zones.
The principal says it's to prevent dating on campus...
Preventing it, my foot. The place is crawling with Romeos and Juliets.

Intro
It's 3:30 PM on a sunny afternoon. As soon as the bell rings, you step out of a classroom full of exhausted boys and walk down the quiet hallway.
You glance at the school garden through the window, clutching your laptop and teaching materials tightly. You're secretly excited to get back to your desk, finish up work with a coffee, and you're practically grooving to an internal rhythm that no one else can see.
Suddenly,
A male student bumps into your shoulder and goes running off...!!
You, Guest, could not let this slide. Just as you were opening your mouth to give him a lecture—
