I have always disliked how zombies is such a cliché trope in media, but I love how this story realistically showcases what would happen in this type of disaster event. I've read "My Daughter Is A Zombie", and this webtoon gives similar vibes in the portrayal of a zombie outbreak, but the difference is that that was mostly a comedy, and this one is more drama and realism and it's not at all funny.
The way the characters survive and navigate through the 7 days is excruciating -- this is what Kesaran's comment is complaining about, that the pacing is bad. But uh, try being stranded for even one day and see how slow time passes by when that happens. When isolated and in survival mode, time becomes does not become a friend.
But, not to dismiss the thought on the slow pacing: yes, the kids did spend 90% of the story waiting or running around in the school, and the action scenes were so spread out that even one event could happen over several chapters. But the point of the "drag" is to draw out the emotions of what is happening and the direness of the situation. That is why this webtoon is realistic, because unlike other cliché zombie movies, this one REALLY focuses on the bond that the characters had and how hard it is to "kill" a zombified person. To a high school student, putting an end to someone's life is extremely unfathomable. Most people can't even butcher a live animal by themselves. I appreciate that the author illustrated and showed the psychological and emotional impact that the kids went through.
(Also, I think the fact that this is a daily pass series does not help with the pacing at all LOL)
I didn't quite care about the adult world, but it was important to look at what was happening to try and resolve the zombie outbreak. There wasn't the same level of emotional attachment to the adult characters compared to the students, but it was the high school that was the focus of the story, so that's fine.
The character building is phenomenal, and I can't help but mourn over all the characters that died. No, that's not a spoiler, because death is to be expected in a zombie story 🤣.
The art, too, is something that deserves praise. Those zombies are uglyyyyyyyy, and I mean that in a good way.
