There's a thing that is standing out to me that I think is somewhat funny, and that is that Yuuya truly just seems to be an allaround stand-up guy. Since he's been a named and very often recurring character from the very beginning, I have been waiting for the point where he would become involved in all this in some more active way eventually, but nope, dude's just chilling and cheering people on from the sidelines.
He really just seems to be concerned with making sure that the people around him are doing well, dislikes conflict, but not in the way that he'd just avoid it but rather in the way that he tries to actively prevent it, or, failing that, tries to solve it by mediating, and back during that thing with Hiroko's boss he wasn't shocked about the rumours that Hiroko might be a lesbian, and rather by the fact that anybody would spread rumours with the intent of hurting her in the first place.
Dude simply seems to be a decent guy who has figured out work-life balance, good for him.
