Movie about a girl see a boy in a middle of a crowd in christmas.

A girl is short hair blonde. She was laughing with her friends and suddenly the boy appear in her sight, and she look at him at kinda stunned. The boy is walking alone.

What is the title of this movie?

That sounds similar to a lot of different films. How old are the boy and girl? Children, teens, young adults? Could it have been a made for tv or Hallmark film? Any idea of how old or new it is?

i think they are teenagers. The scene is in a park full of christmas vibe and the girl is gathered with her friends and from a distance the boy walk into her sight.
