Not/Love is very interesting yaoi manga. Personaly I like it a lot because it wasn't like most of the yaoi mangas where the couple fall in love and live happily ever after or where they easily accept their feelings. Not/Love is very realistic in some kind of way, the main characters have problems that really can happen to somebody in the real world.
Daisuke is a young detective who is trying to find a guy as a part of his job, on his way he will meet Bun, who will help him to find the guy in exchange of stay at his house for a couple
of days. It looks like a predictable yaoi manga until here, but then, you start to discover Daisuke's dirty past and also Bun problems with his family and dirty bussines he is in.
The volume has a main story that show how they meet and started to be together, and them, another chapters where the author shows what happened to them 7 years after that.
I really enjoy it because it was very real but also funny. And the art is very appropiate for this kind of story is kind of realistic but at the same time, fresh and dynamic.
Good thing to point here is that the female roles aren't annyoing. Usually there's female roles in yaoi mangas (like ex-wifes or ex-girlfriends) and usually they're so annoying and just make you want the male couple to forget that women exist and live in their gay world forever. However in this manga, the girls are quite charismatic.
