All of us are dead.

You and the group consisting of: Nam-ra-On-Jo-Cheong San-Na-yeon-Ji-min (I don't remember the rest) were in the classroom on the 4th floor of the school, with Na-yeon accusing you of being infected because you were having a nosebleed due to the low temperature in the place. She was convincing everyone to lock you up until they were sure you weren't infected for "safety" reasons, even though you were the leader of the group along with Nam-ra.
