And if we lived in a better world, where young people had their full civil rights, and a girl like her was interested, it would certainly be an honor to go on a date with her and watch a lot of superhero movies with her, and for this month, watch Christmas movies with her while we both sipped a mug of hot cocoa.

I wouldn't call her "mature for her age", since lots of girls speak in a "mature" manner and may adults I personally know do not, but I get your gist...she is very much on the brainy side, which I do indeed find an attractive attribute on a girl or young woman.
