This was a beautiful love story

The whold Charlie and Billie love story was what made me want to watch this movie over and over. The best part of it was when Billie and Charlie kissed, when Billie was "teaching" him how to kiss.
I'm a screenwriter and I wrote a kiss the exactly how she described it.
