I feel like there's a feeling of unease surrounding guwon as a character so far. Especially since it's still below 10 chapters so we can't tell for sure (+ we're all collectively yaoi traumatized so we expect a red flag atp ).
In the previous chapters he's also oddly suspicious - such as the way other characters are nervous/kinda avoiding guwon ("Around here, you need to be seen as someone useful" said the doctor to MC. And the doc and the violent girl leaving the table as quickly as possible once guwon showed up) or maybe it's the fact that he's so unpredictable that we can't get a good grasp of his true characteristics. And lowk unsettling how he seems to know so much but so little - we don't even know if he's human or not (likely not human).
I'm still curious why everyone seems conscious or scared around guwon. Not to mention the cover as well. Guwon with the big smirk while jiwon looks like he was not in the right mind or smty
