In the big city of steel and concrete, there are little people with different destinies living. They are different in height and have different personalities, but they jointly interpret their own stories for this complicated world. The busy commercial district, the residential areas lined with high-rise buildings, the noisy markets, and the quaint and quiet old streets all together form a beautiful picture. Xiu Hang, a 28-year-old single man, lives in this city. He was forced by his mother to join the blind date camp, met Liu Jingru, a rich girl, and inexplicably became friends with his immediate boss Chen Haoyu. Who is the "mysterious woman" who met him on the phone? A series of "unexpected events" overwhelmed the little man Xiuhang, who was walking on thin ice. Like every ordinary young man, he longed for a wonderful life, but he also had his own principles and bottom lines. He insisted on justice but inevitably had to bow to reality, floating up and down in this ocean called life.
