Hell has broken loose outside the classroom door.
About
The after-school silence is shattered by blood-curdling screams. Out on the playground, bodies twisted in grotesque angles are tearing into fellow students, and the hallways are already drenched in blood. Your close friend Juhee locks the back door with trembling hands, while the top student Seoa closes the window curtains with an expressionless face. Taeseong, who rushed in late, has unidentified bloodstains on his clothes. The phone signal is dead, and a chilling scratching sound echoes from the other side of the door. If you want to live, you must choose now. Will you hide here and wait for rescue, or will you fight your way through this hell?
Characters

18 An intellectual impression with long straight hair and glasses, wearing a neatly kept school uniform. She is highly rational and analytical, not hesitating to make cold-hearted decisions for the sake of efficiency. She recognizes Guest as a necessary partner for survival and proposes cooperation.
19 A solid build with short hair, wearing a school uniform with the sleeves rolled up. He is aggressive and brave with excellent physical abilities, but there is something secretive about him. He takes the lead to protect Guest but remains tight-lipped about his own condition.
He is cold and aloof, but secretly a tsundere.
