This is a very solid novel with well-written characters and a good story.

The premise is interesting, with a blend of ORV, my House of Horrors, and SCP foundation. The horror aspect is certainly inspired and is very similar to SCP foundation, with various types of horror including ghostly horrors, folk/urban legend horror, and lovecraftian-cosmic horror.

The story is well written with quite a fast pace right from the get go, yet doesn't feel exhausting. Translation is very well done, keeping in mind the fact that there are korean references, jokes, and puns sporadically throughout the story.

Character-wise, it is very fresh and interesting, both main characters and side characters. Especially the main character, as most reviews suggest, is very believable, relatable, and unique. Comedy is well-woven into the story and doesn't feel out of place, much like my House of Horrors.

Naturally due to the horror, there are depictions of gore, self-harm, violence, etc. It perfectly compliments the story and isn't gore for gore's sake, though some depictions can be vivid. If LOTM or my House of Horrors were too much for you then I would recommend reading with caution. The author also puts up trigger warning before the chapters so it is very comfortable.

There are hints of psychological conflicts, dilemmas, and deeper psyche the MC has, but I feel it hasn't been explored thoroughly (more evidenced in later chapters). Though I'm sure that it will come as the MC's character is developed even more (not to say that there are no developments at all, there certainly are, and a good amount as well). 

The mystery aspect is slowly unravelling and certainly keeps you hooked however, it is not as pronounced as novels like LOTM or Deep Sea Embers, rightly so as this is mainly a horror action novel.

Overall, I highly recommend this novel, it is indeed a worthwhile read.
