Six people, Lin Yichen, Jiang Nannan, Zhou Lechuan, Xu Leiyao, Sun Yuhao, and Dong Jingchu, were running around in different areas of the city. They met and became friends through coincidence and misplacement. They bluff in the workplace, pretend to be free and easy in love, and hide their worries in friendship. Every misunderstanding and communication brings new growth, and lies, sincerity and choices intersect at any time. In three years, they faced career changes, emotional entanglements, family pressure and self-questioning. They gradually matured with humor and warmth, and finally learned to sincerely face themselves, understand others and accept the imperfections of life. Each volume focuses on a stage of theme and main character promotion, and ultimately leads to group growth and perfection.
