I'm looking for a yaoi manga which I forgotten the name of, but I remember that the seme was an architect and the Uke was a construction worker, then they moved in because the Uke had nowhere to go because he found the semes cat. Then he lost his memory through the manga. There's a squeal to the story about this tanned guy who worked there with a guy wearing a suit. Please and thank you!
