A song i want know...

Hi everyone, i know it's sudden but i really need your help, please share your thought and help me.

It's a long story to start so i cut it short, one day i happened to find a friend (a girl) of mine named me "Nocturne In Autumn" in her phone, I'm quite curious about that since she named most other people normally names. And so i tried to learn more about that, it turned out she named me after a song.

Soon later i found out she learnt piano from very young age, teaching by an old exp teacher, so i bet she actually able to "read" musics.

We have known each others for sometimes but right now, our relationship is just a-bit-more-than-friends. Lately we exchange texts to each others every night (i guess things are improving). Well, the point is i like her but i can't "read" music, i can't read her at all. I also love instrumental music like this song (i once told her so i guess she remembers it). Please tell me what you see in the song if you actually can feel it. Thank you very much...
