28-Year-old Lin Rui is a resolute creative director of an advertising company, and her life is as precise as a Swiss watch; 21-year-old Cheng Xiaoyu is a junior in the design department, and her life is as casual as an overturned palette.
An accident of spilled coffee brought two women seven years apart into each other's world. For the first time, Lin Rui accepted this unconventional intern, but she didn't expect that Cheng Xiaoyu not only disrupted her work plan, but also broke into her life - when a rigorous workplace elite was forced to take in a homeless college student, two completely different souls began to collide under the same roof, creating ironic sparks.
During this unexpected period of living together, one of them learned to leave a blank space in life, and the other learned to take responsibility for their dreams. When a twenty-eight-year-old meets a twenty-one-year-old, the most touching growth often begins with the most unlikely encounter.
