It could mean that the person is about to tell a story where they don't conform to the idea of being a 'good girl'. Maybe they've done things that society might not consider proper for a girl who is seen as 'good'.
Sure. A girl might say 'so i ain't no good girl story' and then start talking about how she joined a skateboarding crew. In her community, girls were expected to be into more 'ladylike' activities like ballet or sewing. But she loved the freedom and the adrenaline of skateboarding, and she didn't care that it wasn't what a 'good girl' was supposed to do.
I'm not sure specifically as I haven't read it in detail. But generally, a graphic novel often tells a story through a combination of illustrations and text. It might be about some fun adventures, or it could center around interesting characters and their relationships.
Well, in the 'blues ain't no mockingbird story', it could be about the connection between the blues as a cultural expression and the story's message. The blues is known for its rawness and truth - telling. Maybe the story uses the idea that the blues isn't something to be made fun of or misrepresented, similar to how the characters in the story might feel about their own lives and stories not being mocked or misused.
The 'Blues Ain't No Mockingbird' is a powerful short story. It likely explores themes like the dignity of the characters, especially those in a marginalized situation. The title itself might suggest that the blues, which could represent the hardships and pain of the characters, are not to be made fun of or mocked. It may also touch on issues of race and class, as many stories with such titles often do.
It's not common at all. The grammar and the form seem a bit off. Usually, in proper English, we would say 'it is nothing but a love story'. The use of 'ain't' makes it very informal and the 'lovea' part is likely a mistake. So, it's not a phrase you'd come across in normal, well - written English, whether in literature or in general conversation.
