I know everyone else thinks the chairman is going to hurt Pilsang but I think there might be a difference in his evil grin at winning Pilsang's heart and making him go crazy with pleasure, and wanting to hurt him or abandon him. I think he might really just be a psycho enjoying his triumph and ACTUALLY FEELING EXCITED ABOUT SOMEONE for the first time, but not planning to ditch Pilsang. I'd assume he'd want to keep having this feeling again and again, instead...
I am old and tired and I like reading and writing gay sm** romance.
