Oh! my! god! This was a drama I took my sweet time watching because I didn't want it to end. Personally I have not read the WEBTOON as I was very impatient and I was honestly looking forward to this one so whether it was a good adaptation is up to the readers of the webtoon and I am simply writing this as someone who has watched a lot of shows and dramas.
Not once did I think about dropping it. Horror isn't my thing but not watching this was OUT OF THE QUESTION. As someone who gets bored and tired easily, this wasn't the case with this drama. It constantly kept me on my toes, interested to see what will happen next. So much that this became a problem as I like to watch dramas late at night, but it was too late for me to watch the next episode as much as I wanted to.
The cast was incredible, I loved their acting and I feel like they perfectly fit their roles. The characters had a certain dynamic between them that kept them together during the show, we got to see the bonds that were formed between them and I thought this was incredible. I was a huge fan of the music choices as well, especially the OST (shoutout to bewhy for that!)

the one thing I didn't exactly like was the monsters, especially on the second episode, they could be a lot better but this was more of a budget issue and it did not affect how much I enjoyed the drama. Other than that, this drama is a big YES for me.
