The Story and world background are good. The horror and mysterious elements are portrayed nicely. This novel's horror theme is based on rules and the rules are very interesting and terrifying. The mc is smart, cautious and has maxed lvl protagonist halo. The only downside is translation quality as there are some gender inconsistencies

I was not scared. Nope! Of course not!! Totally was not reading this at midnight or past midnight. Fascinating thriller with tons of sprinkles of horror. I felt more frustrated at how some of the characters acted only because they seemed to dig their own graves, but that's what kept me on my toes. I only read the free chapters and it was worth it.

I've currently reached around ch 500. The story is very well written. The author seems to have had the whole series planned in advance, so even though things at first may seem confusing, everything has a reason. The mc is logical and neither a saint or a murder hobo. just a college student trying to make it through the week alive. Although, there are perhaps some some things that are worse than just dying. There aren't many characters to keep track of, although the ones there are decently fleshed out. There's the occasional gender mixup common to translations, but otherwise the grammar is fine. If you like survival, mystery, horror, lovecraftian, and suspense, then you should enjoy this.

It’s a good story but the translation is not very decent. If you keeping reading You’ll know why MC looks stupid in the first chapters.
