It's tragic, she thinks, that she had to fall in love with him. He comes for days and leaves for months. She wishes she could just push an off button and quit loving Charlie Weasley. She needs him; even as she wishes she didn't, she needs him.
She wonders why.
Why she couldn't make it work with Ron. Why she couldn't bring herself to take a chance with Fred when she knew how he felt. When Charlie was gone, everything became hazy. Why 'couldn't' becomes why 'shouldn't.' Then he appears in the floo and she rushes to hug him. Everything comes back into focus because he is her remedy. But why? Why can't she just pull away?
Ship Hermione with all the people
It's insane, he knows, that he would fall in love with her. He loves his dragons, his work on the reserve. These are the things that make him happy, but sometimes he goes a bit crazy without her.
He's at a loss for why he can't make himself bring girls home. He is confused as to why he lays awake at night thinking of his little brother's best friend His mind goes into overdrive. Then he goes to The Burrow, which frankly will always be home and she's there. His head screws itself back on straight, because she is his clarity. So why does he push her away?
And then, after two years of the same song, she finally succeeds. The music is gone and she's finally done dancing.
