There's a story behind this drawing, you know.
Here's the story:
"There was once a boy named Luc. He lived in a peaceful village and had a girl best friend, Reika Lawrence. Reika was a cheerful orphan who lived with her grandparent while Luc was a very clever boy who liked studying, yet he preferred playing outside more. He also came from a wealthy family. Then one day, Luc was sent to the outside world to study and soon he became a scientist. Before he left, he and Reika made a promise that they would see each other again in the future. Luc then worked at the laboratory of a certain organization which actually has an ambition of making a winged human whom they called 'Angels'.
