Now you made me want to read it.
Lol
YOU CAN GET GAYER THAN NO.6 !?
XD
At least in No.6 we doesn't have to ship the pair anymore cause nezumi and shion is canon/official couple and I dunno anything bout Uraboku.
There's has alot of josei/shoujo genre that imply shounen ai/romance or Bl subtext to be precisely for example:
Karneval
Makai ouji Devils and Realist
sennen meikyuu no nana ouji
Kuroshitsuji
[Switch] the Hal and Kai is canon if I'm correct
Get Backers Ginji stay with Ban till the end
Hakkenden pure romance sousuke and shino ofc
1001Knights
Omg I write so much well what ever....xD
illegenes is basically BL without a kiss scene. you gotta be kidding me if you think otherwise. this series is gayer than no 6 and uraboku.
