As frustrating the conversation with the brother is, do remember that the only two people that know Eungyo wants to be with Sunwoo is literally Eungyo himself and his brother. Like, up until pretty much very VERY recently for all of them, the impression they have is that Eungyo doesn't want anything to do with Sunwoo, and Sunwoo himself is pretty aware of that despite his delulu.
So like, I don't think Sunwoo and the people on his camp should be like. Blamed for not getting what Eungyo had been VERY vague about. This is all just circle back to that this particular mess is caused almost entirely by the fact that Eungyo wouldn't just. Be straightforward. Like, the only way that anyone including Sunwoo (even taking his delulu into account) can be sure is if Eungyo himself is the one who say it out loud with no ambiguity.
