Deadman Switch Vol. 1 (novel‪)‬

On a Christmas morning that should have been filled with joy, Hohyun wakes to a nightmare. His dormitory has turned into a fortress of terror, its halls overrun with zombies—creatures of blackened gore, driven by a hunger for human flesh. Isolated from the outside world, Hohyun is thrust into a fight for survival, far from any trace of holiday cheer.

In this madness, he meets Youngwon, a figure shrouded in mystery and deadly skill with a fire axe. Youngwon, who seems to know Hohyun’s every move, becomes an essential ally in the battle against the undead.
