This book describes the protagonist's aspirations starting from adolescence. As he meets more and more diverse people and his life experience continues to grow, he finally suddenly realizes that he has not only gone a long way to grow up, but also lost and gained a lot of character and courage. Finally, he returns to an early calmness and embraces his adolescent aspirations and ideal self.
Intention: Growth is a kind of defection from the old self, but we will never forget our original intention, and the beginning and the end will become one.
