As time washes away, bright scars will appear on these fresh faces, and then they will slowly heal with hope. Like us, all of us experience growth, pain, and joy. This book is different from ordinary youth novels. Books that are hilarious to the end will only make people feel superficial. As a youth growth text, the price of growth is to learn to be sad and strong. Read it, you will start reading in a state of ridicule, and then gradually become sad. Perhaps only when you close the book, you will smile knowingly because of the bursts of warmth that emerge, and you will no longer be so sad.
