Paljae, Child of Winter. It's a manhwa and it's historical and has korean mythological stuff, heavens, humans, ascendants, demons. It kinda has danmei type of plot but it's Korean.
Summary:
It's more than just coincidence.
Young Paljae drifts to the isle at world's end to be taken in by Munryeong, a hermit with a mysterious past. But when Paljae begins to waste away in the sun-bathed climate, Munryeong takes his little companion on a journey to the cold north that uncovers their forgotten past encounter.
(It's my fav manhwa, it's honestly so well written and has amazing art, the characters and the story is complex and it's plot based)

Have u tried Guideverse like Hunter wants to live quietly... This one "Wadatsumi no Yometori" is unique if you want to give it a try.
Yes I already did
I already tried that. And it's not really my type. Because ML was a kid when mc took him in.
He's actually not a kid he's just a creature that somehow died and got resurrected, both the mc and ml are a thousand year old and they've met in the past long before that, they just lost their memories. And when mc took ml in, he clearly said that he doesn't want ml to call him father or anything, he called him his companion. Anyways it's your choice but it's not a predatory creepy manhwa tho some people may misunderstand it
I genuinely need new well written manhwa/hua action bls.. I felt like I've read everything.. Like seriously, can't Artists start drawing actually good bls instead of sa ones..
