Is it bad that the thing that really turn me on the most in this manga is to see their wed...

Would that be your new fetish?

If it is then let it only be for the man I marry But yaoi speaking, it's rare they'd show that to you while a sexy scene unless briefly to show you the couple is married or one guy is already married to some woman.

Yea, rings aren't shown that often. Usually the couples aren't married at all or just that neither guy has gone to buy one yet. I looked up 'kink' and 'fetish' definitions before responding to you too lol

I wish I could see more. And I love that couple. So sad it's about to end.
