Fashion designer Xu Zhihe and her boyfriend Cheng Xu co-founded a business for three years, but right before their wedding, her office was cleared out and she was arranged to go home to care for the family. She called off the engagement on the spot, rented Lu Chengzheng for 300 yuan to pose as her boyfriend and help her move, only to find out that he is actually the chairman of an apparel group. Faced with her ex's pleas for reconciliation and work entanglements, she insisted on completing the handover, proved the value of her design through on-site try-ons, and secured her own orders. Lu Chengzheng respected her choice, and the two went from temporary partners to falling truly in love, with Xu Zhihe ultimately winning back the initiative in her career and life.
