Xiao Ran, who was born as a poor student, won the girl's heart, but in addition to love, there were too many practical problems to consider in the future. Driven by the tide of the times and the fate of the encounter, the good buddies came to Shenzhen, the forefront of reform and opening up, which was full of opportunities and unknowns. Success, depravity, friendship, betrayal, love, money. In the bizarre coastal city, ideals and material desires collided fiercely, and young people spent ten years considering their hearts and souls...
