Im seeing that a lot of persons replied under a different question that their first yaoi was either junjou romantica or Sekaiichi Hatsukoi. These were the first yaoi I read as well so I wanted to know how much person had the same experience.
To be honest, I really don't know, probably some random Haikyuu comic on Youtube, most likely Kageyama x Hinata (YAOI) by ChemicalAngel or something like that reply
