I was waiting for the two tops to get it on together…not even a freaking kiss?!?!

"Konna no Unmei Janai Kara Kanchigai Shinaide" I think it's also called "There's No Way This is Fate" it also had a sequel "~Newlywed's Arc".
I don't remember if the tops ever get "together" again after getting with the bottom, but they were kinda together before, and definitely still hold affection for each other, as well as the bottom.
Basically three best friends, and the two tops were always both in love with the bottom. They used each other as an outlet for that love for a while, before all three become a thing. Both tops agree they would have been a couple if the bottom weren't in the picture.
“Marriage demands sacrifice and change from both sides. If you find that you’re sacrificing nothing, that you’re not changing at all, then perhaps it’s worth asking whether your partner is carrying the burden for you.”
You hear that? That’s what wisdom sounds like.
