TL;DR: What if the female protagonist of a horror manhwa just... refused to believe that she was in a horror story because she so desperately thinks she's in a romance fantasy? You'd get this--part horror, part romance, mostly just goof. L;DR: Look, I've been around the otome-isekai block for years. Here's something a little different for all my other OI elders who are so sick of the same repeated plot lines. This manhwa does an excellent job of tone whiplash. It's ominous while simultaneously being incredibly endearing. Lovecraftian horror meets the female lead's genuine delusion, to a result that actually provokes genuine laughter outof me.

Yes, the female lead's total obliviousness does kind of get annoying after a while, but the story deals with her tremendous plot armor in a pretty self-aware way. It's not a life-changing read by any means, but thoroughly enjoyable and refreshing in a deluge of everything else. Give it a shot!
