I’m not sure, but sounds interesting. Also, there’s this but it’s not a manga https://www.mangago.me/read-manga/love_me_revive_me_official/
Thanx!
I not even sure if the one I’m looking for is a manga. It could more likely be a weebtoon, I just remember reading it here. I read like 5 chapters and then my reading list got wiped. That’s why I don’t remember the plot. I think the uke was some kind of ruler of the city and that’s why he didn’t wanna risk being exposed by seme

After my “want to read” list got wiped, I can’t find a specific manga. It’s about a uke that is blond and in some kind of forbidden relationship that also kinda toxic with a seme with darker hair. I think it’s in a society where people don’t age so I think the characters were probably over 100 years old but looked young like in their 20s. The uke comes from a wealthy background and I think the Seme does too. The uke wanted to break off their relationship to preserve their relationship but the Seme continues intimate relatship with him
