Can anyone tell me why is it Jose I and yaoi at the same time

When something is Josei it doesn't exclude it being Yaoi, unless you think that Josei tag is exclusively meant for harlequine mangas, mangas about relations of mature women and such, or Yaoi being only for gay guys (it is about them, tho). Generally speaking Josei means something meant for young women, older than teens and we know that majority of Yaoi readers are women/girls. So this gives us the result of this being labelled both Josei and Yaoi.

Ahhhh thanks a lot
my dumbass brain thought it is about love triangle with both boy and girl????? I'm so stupid
