In the autumn of 1994, Lin Maimai, a girl from the northern mountain village "Xinghuagou", gave her most precious thing to her boyfriend Zhao Lei the night before he was admitted to the provincial university. In order to keep this relationship, Xiaomai went to the city alone with her family's only savings, only to find that Zhao Lei in the city was no longer the young man under the old locust tree at the entrance of the village. Emotionally ruined, penniless, and sleeping on the streets—just when Xiaomai was desperate, college English teacher Chen Shubai reached out to her. With a pair of scissors and a second-hand sewing machine, Xiaomai started by setting up a street stall and sewed his own world step by step. However, the entanglement of old love, the villain's schemes, the dangers of the shopping mall... Every obstacle is testing this stubborn girl. She sewed together a career and an unforgettable love with her hands.
