Thank you for sharing! Kiyoto, to me, very much gave off the vibes that KNEW he liked Touji more than Touji liked him. From the start it seemed like he was ready to just be there for Touji instead of getting serious. I didn’t even notice Yachiyo stopped wearing his ring. I’m glad he’s divorced (since it wouldn’t be fair for his wife)
both aren't mutually exclusive tbf. i thought that even if he thought touji needs to settle his past grievances, he would tell him to go do it but ALSO tell him that he still likes him and is willing to be with him if touji ever thought of wanting so. but he didn't, he just chose to break up. also tbf though i dont fully know how the break up came to be so maybe he did say that. just that, if he didn't, it's likely that he just have his own problems to deal with and isn't willing to fully dive into the mess that that would potentially cause (touji still liking yachiyo and him having to wait for touji to settle that)

thanks to user salvxx in the raws site for explaining this:
"Yachiyo’s been divorced that much should be clear just from the fact that he stopped wearing his ring.
Kiyoto broke up with him (Touji) bc he could tell what happened between the two of them was largely unresolved & the stress of worrying about that every time the two of them met up was just not worth it (not to mention his first encounter with Touji was literally right after Yachiyo’s wedding so he knows exactly how much realizing things too late fucked Touji up). Touji was definitely trying to make it work but being in the thick of it probably couldn’t see things as clearly as Kiyoto was as a bystander."
I understand Kiyoto tbh but I definitely thought he'd fight for Touji harder. I guess he has his own problems with himself to deal with as well.
We can only see what the future volumes will give us.
