Someone knows other stories like that? I feel like reading something similar while waiting for this one to update
Erm... that would be hard to find. However u could try this for a fun read https://www.mangago.me/read-manga/cairo/
That's still quite broad... haha. All the aspects you mention can be found by clicking in this story's tags, and usually you can find them seperate, not together (for example, most ancient Egypt stories here are shoujo, not yaoi, so...). If you like the Seth x Horus dynamic ("younger guy who meets older villain who turned bad due to being betrayed, and wants to save him") then I guess you may like a story like Gonzo's Gankutsuou... but other than that, I dunno what to say because still I'm not too sure what you're looking for...
It has no mythology but plot and chatacters are top notch. I recommended The Beast Must Die. It has more than just sex scene actually even the sex scene is meaningful in more ways than just sexual satisfactory fulfilment. After I read it, I had to go research the main point of story, same way as I did with ENNEAD
Alright two sad chapters here we go. I hope He Tian and Little Mo will make up cause even though I understand the frustration of losing his job, it would be stupid to leave their relationship strained as it is right now. Also kinda irrelevant but I like how observant Zheng Xi is. The man doesn't talk much but damn he knows what's up
