Lin Yi grew up in a welfare school and through his own efforts was admitted to a good university, majoring in computer science. After graduation, he entered an Internet company and became a programmer at the lowest level. With no family background and no network resources, he is the epitome of thousands of "migrant workers" in the city. He doesn't have many unrealistic illusions about life. His biggest wish is to pay off the loan early and live a life without having to look at the boss's face.
