When Youan is one year old, she is really one year old, and when Youan is two years old, she is really two years old... When Youan is seven years old, she knows that she is seven years old. Five years later, they said that Youan was twelve years old, but Youan only remembered that he was seven years old.
When others have grown up, she will always stay at the age where she likes to eat cakes.
