I am looking for an adventure movie. It was about a boy who moved to a game (probably). He was in some Asian place and saw some girl there. He was also looking for fragments of a flute. I think the boy was in a wheelchair, but this fact I might have mistaken. I remember that at the end the girl who he saw in the game was rescued on a silo (or some high object) because she wanted to jump.
Every guess will be helpful. It is Asian (Chinese or Japanese) movie probably.
