ML may be a little obsessive, but I think we all knew that from the get go.
I think the you can't escape me works in this case, bc MC wants to runaway bc he feels like a burden and he is sorry. He is not scared of the ML. We've yet to see, but while Shin has super obsessive thoughts he doesn't tries to not act on them - he held back for example when he went to get mc from his apartment, he also didn't go straight to him in the hospital.
I don't mind the violence inflicted upon the grey haired dude -
And red head apparently became braindead bc he fell off the balcony while running away. Seeing how unwell Yeonwoo is I'm not sorry for him either.
I think the disconnect comes from us not being able to see his thought process and him being a little thight-lipped this last chapter.
I hope the manhwa includes all the casual touches between them, this story is slowburn but the ml is super clingy and the mc let's him and it's so cute to read
