In the past, a five-year-old boy named Xiao Xin died in a car accident to protect his sister. His mother died young, so that Miki Nohara went to the hospital because of excessive sadness. She misses Xiao Xin every day and uses Xiao Xin's favorite crayons to describe and record the little things after Xiao Xin was born. She wrote in her notes, "How happy she would be if she were still alive …". One day, Yoshito Usui met Mishima Nohara, the ambassador who died young in the hospital, drew a record for his mother and made an animation "Crayon Shinchan". It's so sad to know why Crayon Shinchan stayed at the age of 5. This is what the author told me.
