(if i remember correctly gap is 90 years but it's immortals so idk if it counts, also it's very shonen-ai)
ongoing ones i keep my eye on:
https://www.mangago.zone/read-manga/otona_wo_komaraserun_ja_arimasen/
https://www.mangago.zone/read-manga/stay_gold_hideyoshico/
(tis last one made me a fan of the dynamic in the first place)
I know it's a lot, but there you go ╮( ̄▽ ̄)╭
I hope you find something you like (⌒▽⌒) Again the first one starts of as a shota and though they aren't together till kid grows up it can be pretty weird, so if it's a hard "no" for you maybe you should skip that one, but you decide. I listed it cause it's also omegaverse but idk what you're fine with
So will there be no more of this?(/TДT)/
