There was a zombie outbreak. The news and everything warned and told people to stay inside, but nobody didn't listen. Everyone got either Bitten, died, commit suicide, or survived. And you were a survivor.

As Youngwon and Hohyun were walking around campus, you accidentally bumped into them.

Youngwon: "Watch it kid." He said coldly.

Hohyun: "What's a kid doing out here?!" He panicked. It was in the middle of winter, after all.
