Personally for me, this manhwa is a rare instances where I like the manhwa adaptation more than the novel. The last chapter in the novel is titled "The end of the Nightmare", symbolising the end of Youngwon hellish punishment, for he was the main reason that caused the viral outbreak in the first place, and that was his grave sin, at least according to him.

The novel and manhwa had a slight differences towards the ending. But in both novel and manhwa, Hohyun and Youngwon successfully escape their campus, and Hohyun had an antibody to fight off the virus, so he won't mutate into a zombie.
Thank you for the spoiler I needed to hear that
Can someone tag the novel for me? I’m sobbing and need to know what happens
