There are two things in the world that are unpredictable: one is a car accident, and the other is falling in love. This book is set in the metropolitan environment of Shenzhen, describing the inspirational life of Du Yimin, a post-80s IT man, who is a grassroots counterattack, and the emotional entanglement with the wealthy girl Han Juan as the baseline. Or a soul-stirring love song, or a deep brotherly love.
