Is it this?? I don't remember much but it does fit your description of the story alot
Yes thank you so much !! I search for one hour
I dont remember the title but this is a BL, not an omegaverse. The two guys switch between top and bottom. The older guy is an architect and at first hé was the top. The younger one is a mason if I remember right and when the relation between the two start he was a really cute guy but he turn into a sexy guy. The story is about the change in their relationship and how they become a switch couple
Thank you for your help
