This is kind of mid, but depends on what you like to read. The slow burn was understandable but also just really frustrating, the communication was lacking most of the time, and they mentioned the redheads family only to never visit that idea ever again, or explain what happened. Felt like a useless plot-line. Also, just for anyone who is into this kind of thing: Sangwoo very much gives off neurodivergent vibes (mostly autism, and they even stated they've tested for OCD), but they were SO insistent throughout the whole thing to say things like "he's normal" and write it off. If something like this was explored, it could have made the slow burn a whole lot better. Personally irked me but its not that big of a deal in the grand scheme of things.
TLDR; the plot is mid, but if you want a mindless read, go for it!! (๑•ㅂ•)و✧
