@Umesan ok, I get where you're coming from. I have a similar thing for mangas with no chapter titles, where you have to look into the chapters themselves to remember what they were about.
However, I'm kinda hesitant to put names into the titles. Main reason being that I've seen plenty of comments where people think Shibakusa/Kinjo and Muramatsu/Kamiuchi are couples, whereas to me nothing seems to suggest that the author even considers them couples (or intends to turn them into couples), even if there are a few chapters where they appear exclusively together. I'm concerned that people may get the false(?) impression that Shibakusa/Kinjo and Muramatsu/Kamiuchi are something more than they are meant to be, since titles are supposed to be kinda official, and if someone sees "Muramatsu/Kamiuchi" in the title they may go like, "hey, there's hope for those two, huh!"
Maybe I'm making too big of a deal out of this, but I also don't want to needlessly raise anyone's expectations 😅
And then there's also the fact that I simply don't know which names to put into the titles. Some chapters aren't focused on a "couple"; do I just skip those and only mark those chapters where I can clearly identify the pairing? Do I mark every MC that appears in every chapter instead? If I mark every MC, do I mark them also if they just appear in the background and don't contribute to the chapter? Do I really mark the Enokida/Aritsuki pairing despite the fact that they are hogging 90% of the chapters and that'd be a lot of visual noise?
It's just hard to decide what the right thing to do is, really. But sticking to just normal titles is easy, so I think I'll hold off on adding names anywhere. Sorry for the long text 😅
