Can't remember honestly haha!
but I'll ask my friend.
One yaoi has to do with a vampire & mortal & my gawd that was a good manga.
Another has to do with a famous novelist & his assistant.
Another yaoi is called "loveless"
There is this one manga (it's not yaoi) but it's called "perfect boyfriend" I think that's what it's called. It's very good & addicting.
