Fiction: Playing a Game

So - I have this scenario in my head, It's a metaphor for something, but I am not sure what. Anyways,  I think it is a cute short story.

The Game

Imagine two people playing a game, it is a variation of "tag".
One boy and one girl.

     "If I catch you, I get to kiss you". he says

The boy is "it".

They are running around and laughing.

She is not running as fast as she can, but she makes sure to stay just out of reach. She doesn't seem to want to be caught, but likes being chased.

The boy isn't running as fast as he can either, he doesn't seem to want the chase to end.

This goes on for a while. sometimes the girl will peek out while hiding behind a tree, or call to him to get his attention. Sometimes the boy nearly catches her, his fingertips barely brushing her sleeve.

Suddenly the girl stops, she turns around, and opens her arms.

He tries not to crash into her, but It's too late!  He can't stop, they collide <glomp>
He's worried that she'll be hurt, while they are tangled up, he manages to turn so that he takes the impact of the ground on his back. Some of the air is knocked out of him,
"oof!"
 He winces.

He opens his eyes and looks up at her. She's wearing a mischievous smile, her eyes are sparking. She is beautiful . Sunlight is streaming in between the stands of her long hair that seems to form a veil around their faces.

     "I win!" she declares, as she leans down to deliver a kiss.
