I also remember that the uke had a friend who was orange haired ( idk if im right about this tbh) but at the start they went to a mountain to perform a ritual but it "didnt" work so they went back home( they live together) and while the uke was showering the seme appeared behind him and thata when they made that deal/contract
At first I thought it was https://www.mangago.me/read-manga/shaman_s_house/ cause blonde, black haired and had gods involved. Tbh I just skimmed thru your wholeass paragraph haha until I saw 2023 and the second part.

. It's really similar to it's just a dream..right? And my delicious dreamboy, story wise and art style.
It's been a while since i read it so I dont remember alot
All I know is that the seme is blond and the uke is dark haired, there was a side character as well he was dark skinned and dark haired as well he basically was a friend/ bodyguard of the seme
The seme isn't human but the uke is.
The seme isn't an incubi or smth but I remember him having wings or him having some kind of powers, the uke is protected by multiple gods due to him attracting alot of bad spirits. I remember T the beginning the seme made a deal with the uke cuz the god that protected the uke took away a sum of the seme's powers, so he made a deal with the uke so he can get his powers back. It's not SUPERRRR smutty but it does have smut. That's about everything that I remember. I read it in 2023 and it was completed if im not wrong
I looked thru my lists but unfortunately couldn't find it cuz most of the mangas/manhuas/manhwas I added were removed.
