I want recommendations for mangas that aren't boys love that has some casual gay characterand, that it is not a manga entirely about LGBT issues

Like Hoshino, Me o Tsubutte or Mirai Nikki, mangas that happen to have a gay character

Can be any genre of manga or manhwa, except bl

Preferably not very well-known mangas, because I already know most of the well-known ones

Coincidentally, I just happened to come across Boku ni Natta Watashi the other day. That fits.

Have a gay man character?

Quote from larissamura

Have a gay man character?

No... as you requested, it's a non-BL manga. It's about a girl who goes undercover at a boys' school. Main couple is a straight couple. One of the side characters is a gay boy.
