Ron is deepyly in love with Hermione, and doesn't know how to tell her in words. So he sings it to her in a song. ~That night I worked hard on thinking up a song. It took me all week, but I finally had a few verses down. Of course, I was so zoned out that I had accidentally changed my sofa chair into a small dragon in Transfiguration, but I had finally finished it. The perfect song for the most perfect being ever.~
