WWTBC - Established Older Couple

So I haven’t actually read this book yet but I remember saving it to my TBR list and unfortunately a bunch of stuff has now gone missing from my phone 😭 what I do remember is a drawn image of the main pair on the cover embracing on what looked to be a mountain peak or something similar?

I remember reading the description this story was supposed to be a fairly low angst story about a couple (both maybe in their late 40s/50s) who had already been together for a very long time, and were about to move onto a new phase in their lives.

I really don’t have much else to go on and it’s a bit of a shot in the dark, but if anyone has any ideas on what this book was, I would greatly appreciate your help!
