The only one I can think of is love is an illusion 2nd couple. Here's a link to the story. Chapter 107 is where it starts the conversation it goes on for a chapter or so.

I'll finna cry. I thought I read something recently with a seme that said the same exact line but I couldn't find this ╥﹏╥ I thought it was Omega Complex but I couldn't find where he said it. I believe it was a manhwa or something that wasn't short. I also have a feeling it was something with a seme that's puppy clingy type. Or maybe it's my head playing tricks on me. Idk but this is so familiar and I thought I read it recently or it was completed recently ╥﹏╥ my brain why
Currently looking for a bl that I came across a while back... I don't actually remember anything about it except for a line in the end when the seme(?) tells the uke something along the lines of not being pressured to have children and "we will spend our time loving each other and if we decide to share our love with others (kids) then we will do so then" (reassuring/comforting type scene).
