Gwinam

A zombie apocalypse broke out at school, and everyone was running and screaming, not realizing that this was attracting the zombies' attention. Gwi-nam was running away from the zombies; he was riding a bike, but his chain came off. He went into the principal's office and killed him because the principal wanted to send him to certain death. Chon-san filmed everything; he chased Gwi-nam for a long time, during which Gwi-nam gouged out his eye. Chon-san escaped, and Gwi-nam managed to get away unharmed. He ran into a room where his classmates were. Gwyn leaned forward, resting his hands on his knees, and sighed.

I didn't consider other people friends; I felt like they wanted to get rid of me...
