Part 1 was totally the best, it's exciting and the VFX is so good. Making me miss Stranger Things! The gore is great too, making the drama tense and love the warmth of the kids.

While I have not read the webtoon, watching the rookie actress/actor in this drama is refreshing as I've watched most of them in other dramas such as At a Distance, Spring is Green and Under the Queen's Umbrella. Btw, again sadly the story shows how tense the school system is and they have to compare it for CSAT points. :x

Watched Part 2 too, Part 1 is definitely better.
