I guess this is kinda a mix of everything which most is family regret with father and daughter and things like that
P.s: some of these I haven’t fully read so take everything with a grain of salt
Okujima Hiromasa, Takahashi Hidebu, Est Em, Okadaya Tetuzoh, Asada Nemui, Totempole, Kajimoto Reika, Mentaiko (geicomi dj mangaka influenced by famous shounen/seinen stories), Iwasawa Midori, KOIKE Sadaji, ARAI Niboshiko, etc (the space here is limited, so no more creator names)

A very good list from RoseMary: https://www.mangago.me/home/mangalist/226060/?filt
Pls, don't pretend we are only here to read pure shounen-ai love and romance. :D :D :D
Just saying, hentai/porn BL is also BL.
