following cuz this my cup of tea but here are my lists of that exact kind I have for contribution
https://www.mangago.zone/home/mangalist/2833883/ (older ukes that actually look old)
half of the stuff there is completed i think? some are also false ongoing (completed but status not changed)
https://www.mangago.zone/home/mangalist/831694/ (Older/Tan/Manly/Seme-Like Uke with Younger/Prince/Girly/Uke-Like Seme) basically a masterlist besides the uke being older. same thing with above list with completed stories and false ongoings.
not sure if some are good but hopefully u can find urself one in any of those hahahah
I just read high clear and it perfectly suits this though the uke is younger then the seme
Can you please recommend some good completed yaoi manga or manhwa where the uke is older or taller or bulkier than the sème
Thanks
