In a modern city intertwined with countless dreams and trivial matters, six young people including Lin Zihang entered the society, embracing their own ideals and confusions. Workplace, emotions, family, career. They met, collided and grew up in their stumbling lives. In the face of pressure and misunderstanding, they used humor to resolve embarrassment, used enthusiasm to dispel depression, and moved forward hand in hand in a metropolis full of episodes every day. Their youth is not a shining miracle, but it is real and wonderful enough. The four-volume story intersperses career progress, emotional entanglements and life changes, and revolves around dreams, reality and self-salvation. It is hilarious, tender, sad and growing all the way, and finally ends successfully in friendship and self-realization.
