3rd list: https://www.mangago.me/home/mangalist/3746699/
(IF 1ST LIST IS FULL, I'LL MOVE OLDER ONES TO MY LIST 2&3)
Contains all old man and middle-aged man BL I could ever find. All of these guys are 35+(I know 35 year olds are not old men, but according to BL standards, they are). Mostly contains BL with old ukes or both of the guys are old men. There are some with old man semes as well, but it depends on whether I read them or find them.
My pfp is Keith & Shin from:
Tokyo M-Mesu Hard-Boiled
(東京Mメスハードボイルド)

Any JP raws that I've uploaded from my
uploads tab will show as "This chapter
was removed, return to [Story Name]"
when you click them, so just go to
the stories main page and they'll
be in the raws section.

I sometimes translate JP extras
that didn't get English officials.
