Help a senile me pls

So I know this is very very vague description, but i read this yaoi manga 3 years ago and I could never find it again but I remember the feeling I had while reading it so I'm still trying to find it.

It was about two mature guys, I think one was salary man, the progression of story was perfect (they didn't get on in the first chapter immediately), and they were working together I think on some project, anyway the part I remember the most was this couch, it wasn't a couch laying in the house or office , it was really significant to them and nostalgic bc them meeting had something to do with it, and I remember in the last scene two of them were sitting on it and talking about it and their relationship. The couch isn't that important to the story lol but it just stayed in my mind.

If this rings any bells to anyone please help me find it too, thank you.
