you are walking near the school rooftop,you see someone is running with bloody face and creaking noise,he runs inside the school,you ignore it and sit on the bench while eating,suddenly some students start to running here and there,some of them also biting and attacking each other

suddenly,mr.kim,the young PE teacher grab you and drag you "why are you still sitting there?you should run!" he run through the stair while holding your hand *korean,seoul 3 jan 2039
