별에게 소원을

Everyone has a wish in their heart that they want to fulfill. That's why when shooting stars fall in the night sky, some of us make a wish, either earnestly or vaguely. Here, this boy made a wish while watching the stars fall that night. He made a desperate, yet somewhat strange wish.... and, miraculously, it was granted.
...except that the wish turned his life upside down!
