That's when Charlotte realised she was in love. Because Millie was beautiful and charming and there for her at every turn. And when someone wakes up in the morning with panda eyes and burger mashed into their ball gown, and you still think they're the vision of beauty, it was time to admit you were truly smitten.
And Charlotte hadn't fallen in love and got hurt because Millie did something awful. It was because she was wonderful. And she was Millie. And Charlotte wished she could go back in time and quiet her beating heart.
