reccs for old mature hot ml?

can i get some reccs for romance mangas/manhwas with old hot mature male leads. or a list if there is one bc i cannot find any.. like male leads like reemployment life with an unsociable untalkative magician, nd the demon king from jk haru wa isekai de shoufu ni natta, plzz

or even just really mature ml for any romance manhwa in general, straight + bl.. reference would b like the ml from no moral, he is so fine
