This is a story about Tony Box, who never went outside of there cabin for the rest of his life. Tony Box lived with his Auntie Box and Uncle Box. Because his Mommy Box and Daddy Box died in a car accident a long time ago, when he was 6 years old. He was with his parents that time. Because of the car accident he never went out of his cabin for a long time. After that car accident he never spoke a word. The Doctor said  because of the car accident, he became traumatic. "He must not see cars and people that can be trigger to remember that day". 

But one day, when he grown-up. Tony Box heard some voices of people outside of his cabin. 

Too loud, too noisy for him. But his innocent look bring out his curiosity. So he decided to go out.
