Ji-Woo stands outside of her school, watching as all of the other students pas by, never bothering to notice the plain girl that stands off to the side. But one thing catches her eye, a person she never fails to miss in a busy crowd. Gongchan's presence is bright, never wavering. Ji-Woo can only watch him, admire his handsome face and beautiful smile. The kind of smile that spreads like wildfire, brightning up anyone's day.

Watching from afar, the invisible girl wishes she could he one of those people close to him, like those best friends of his that never seem to leave Chan-Sik's side. There are always people swarming around him like bees, and Ji-Woo wonders if he thinks of them as just an annoying buzz or if he enjoys their attention. To her he is the sun, and she knows that there are other people that feel that way but is it as strong as what she feels? With a father that ignores her, and only companion a stray cat that has taken a liking to her and a school counselor that can't truly understand what it's like to be invisible and too timid to change that? He is the sun, but she can only admire the warmth it brings to her surroundings, never understand what it's like to feel it's warmth. It's like having to stay inside on a nice day, not being able to enjoy the weather, but knowing it's nice outside.

Ji-Woo know's she can't complain because it's her own fault for being too timid and shy to do anything. But isn't there anything that can change, to make her be a stronger person? To be able to do what she wants without worrying over nothing? If only something would change....
