Examination was originally the most important subject in Lin Kexin's life, but her growth caused her nerdy nature to slowly change. When encountering more and more things, no matter how worry-free a person is, they will learn to accept and change. This book does not contain campus love exclusive to wealthy families, nor does it contain sudden bursts of character. Instead, this book is just a group of ordinary people who work hard and want to see others clearly before they reach adulthood, and they also want to see themselves clearly. Why is high school worth remembering? Maybe because it is the last time when we are still passionate, pure, persistent and brave and far away from compromise - family, friends, or the hazy but distant him in our minds.
