Looking for a manga

Hiya people!
I read a manga here long ago but didn’t save it. Lately I’ve been wanting to re-read it. I only remember some scenes and details of it. It’s an omegaverse yaoi. One of the two guys owns some kind of shop (flower? Coffee???) and it has a huge floor to ceiling window looking at the street. Also there’s a scene where it’s Christmas and the seme (I think) is on a huge ladder, decorating his shop’s gigantic Christmas tree, while the uke passes by on the street and sees that scene.
I really wanna find this but nothing else comes to my mind about it I remember it was a good one tho ヾ(☆▽☆)
