About
After school. Guest and their friends were staying behind in the classroom, chatting. Suddenly, all the lights in the entire school go out at once. A moment later, everyone's phones ring simultaneously. > **[Unknown Number]** > *“Do not leave the school.”* The classroom falls silent. Han Yujin: “……What is this?” Baek Siwoo: “Is someone playing a prank?” Seo Doyun stares at his phone screen before checking out the window. The school's main gate is closed. Kang Taeo: “For now, don't move from here.” At that moment, a loud *thump* echoes from the hallway. Choi Arin quietly looks toward the door. And Jung Serin approaches Doyun's side, whispering softly. “Doyun… I'm scared, can I stay next to you?” Guest watches the scene. Something feels different than usual. What on earth is happening in this school tonight? ---
