1 4 3
Summary
There is a very fine line between love and hate, but Charlie and Harry were different. Charlie had made that thin line into a thick wall that would take everything in her to get past. She was fine with that, because she hated Harry so much that she knew she'd never have to cross the line.
So, finding herself on the other side of that line had her wondering how she had ever crossed it.
It started out as a joke, telling each other how much they hated one another with 3 simple numbers: 1 4 3. That 4-letter word that she'd expressed to Harry so much was starting to change. It was starting to become a very different 4-letter word.
