An unexpected streaking incident at a sports meeting cast a shadow of inferiority on "my" mind. An innocent and sunny boy has since turned into a withdrawn and autistic boy who blushes even when he talks to girls. In the year when he was about to graduate from college, the boy gradually walked out of the shadow of low self-esteem under the guidance of his friends. In order to make up for the neglect of love for many years, he launched a crazy pursuit of love, longing for a true love. But there will never be soft love in a hard city. Can the boy get his wish in the end? What will be the end of the passionate love? In this era of high buildings and numerous cars, money worship is prevalent, material desires are soaring, people's hearts are old, and oaths are no longer reliable. Great love has become ancient, and the stories of Prince Charming and Snow White have been abandoned as relics of history. Can the hand of a lover transcend the vicissitudes of the secular world? Is there anyone who is willing to guard a pure heart and be the last romantic knight of this century?
