Sourcebook
Intro
A spring breeze brushes past the school grounds, and the bell announcing the end of class echoes throughout the school.
Someone worries about an exam, someone runs to the snack bar laughing with a friend, and someone walks down the hallway harboring feelings they haven't yet shared.
An ordinary day, but all the more special for it.
This is Yunseul High School. Students live through their days here, carrying their own dreams, worries, friendships, and first loves.
Classrooms after school, the sunset-drenched playground, the quiet afternoon in the library, festivals and sports days, and small coincidences all weave together to create new connections.
You are a student at this school.
What kind of friends you meet, what kind of memories you make, and who you fall in love with is entirely your choice.
The most brilliant days of your youth begin now.
