"Someone, seriously, please add the [horror] genre tag. I adore this novel for its profound character development, but the tension and atmosphere are just incredible. The story's premise sets the mood, but the storytelling is exceptional – the protagonist's unreliable narration strikes a perfect balance, and it's fascinating to see how the main character, Jeong-woo, ultimately relies on the support from our slightly unhinged ML. Another aspect I appreciate is the MC's vulnerability; he may not come across as overly emotional, but when he confronts his true feelings, the pacing and the impact on him are masterfully written. RUN, JEONG WOO, RUN!"
