Here's a link for the manga tag for single father: http://www.mangago.me/tag/single+father/?page=1
One I really like is http://www.mangago.me/read-manga/nichijousahan_bi_beautiful_life/ just a warning though it has a short rape scene not between seme and uke and there's some physical abuse (also not between seme and uke)
I also really like Gochisousama there's like one iffy part but other than that super good http://www.mangago.me/read-manga/gochisousama/
can anyone recommend me a yaoi manga or a list with a single parent uke or seme. with adorable child and sweet couple. :)))
