I’m absolutely confused did sangmin not have a crush or like jinhyan like I remember somewhere like sangmin was like touching him as he’s asleep or like sick
I think it's more of an obsession to ruin him and he's planning it out slowly when he act as his friend for so many years, since high school, and his shitty father made his character even worse so maybe the way he's touching jinhyan is like with his own agenda, which adds to the creepy vibe that he has. Sangmin's feels like a sociopath to me lol since he enjoys killing his pets cold-heartedly
TLDR: Sangmin yandere lolol
Sangmin's obsession jeez, such tension...all cause of that shitty father. This father and son duo gotta gtfo
