So I'm looking for incest yaoi mangas where people around the couple know and deal with the relationship. Let me be clear; I am looking for titles where the people surrounding the couple know of the incestuous relationship and and adress it. It doesn't matter if the couple breaks up or stays together (Although I do prefer a happy ending).

I have read yaoi mangas where the couples struggle with the incestual relationship and they stay together but, they don't tell other people (Not Equal/all by Ogawa Chise). I have also read manga where incest was knowned and accepted but because of special circumstances (Vampire Knight; vampires are allowed). I guess I can read mangas with hetero couples too.

I just want mangas where not only do the couples struggle with the incest but the people surrounding them also know and address it by either accepting it or opposing it.
