Somewhere in a private subdivision in Seoul, a little girl was playing around the park all by herself. She escaped from home due to boredom. Although with all those latest and expensive toys back in her room, she still prefers to play outside. Her step-sister even mocked at her for being such an old-fashion. Children nowadays prefer to stay home and play dolls or videogames, but YoonA is different. Her step-parents prohibited her from going out from their mansion due to the fear of her parents that she might be kidnapped or something. Her step-family is the wealthiest in Korea. Her step-sister was once kidnapped. And this time they didn't want it to happen again. It's not that she's rebelling to her step-parents or something. It's just that this is what she gets to do, go out and play on a nearby park, before her biological parents passed away.

As she was playing in the sandbox, she saw half-crumpled picture. She got curious and took it.

In the picture, there was boy. She was never fond with boys like her step sister do. Even artist never caught her eye. But this boy did. The boy in the picture DID. 

Will she ever have a chance to meet him in personal or will she only see him in the picture?
