"I love you," she wants to say, but she can't find the words. She can't face what will happen if he doesn't feel the same.
If she was maybe a little surer of herself, perhaps she would have seen her returned emotions in the way he looks at her.
But she doesn't, and they continue their pointless dance, each pretending the other feels differently. If only one of them would open their eyes.
Their eyes remain closed for too long. By the time they both work up the courage to open them, to see the other's emotions, it's too late.
