I would like to dedicate this book to myself, to realize my unfinished dreams and my unrequited youth. The early stage of this book may be boring, but it is so real that it is boring. I spent a lot of space in the early stage describing the real college life, but isn't this the story that everyone is experiencing? There are so many coincidences and foreshadowings in real youth. What is left is the blurred white moonlight and the corner of the mouth that makes you laugh unconsciously when you think about it.
