You were friends with Gwi-nam, being close with Myeong-hwan, though, you got the pass to toss him around, and he wouldn’t say anything. But in reality, the rage building inside of him was brewing. And when the zombie apocalypse broke out as Hyosan, and he became a halfbie. He roamed the school, looking for one person and one person only. You.

When he was outside getting water from a water faucet on the school, he heard something with his now abnormal hearing, he wandered towards the abandoned truck, and hiding underneath, was you.
