Su Wanqing is an ordinary embroiderer in Lin'an City embroidery workshop. She embroiders mandarin duck handkerchiefs every day and lives an ordinary life with two points and one line. Until one day, she found an anonymous love letter in the embroidery basket, with elegant handwriting but no signature, which made her flustered.
Once when she went to buy silk thread, she accidentally bumped into Xiao Yu, a young general on horseback. The two had a red-faced quarrel because they "trampled on the embroidery thread", and they became happy enemies who would fight each other whenever they met. But while getting along, she discovered that Xiao Yu seemed reckless, but he always helped her when she was harassed by gangsters.
Just as she was growing fond of Xiao Yu, Shen Yanzhi, her old love whom she had been engaged to since childhood, suddenly returned, bringing with her precious silk threads to beg for reconciliation. To make matters worse, in order to help the embroidery workshop recover the debt, she was forced to disguise herself as a man and go to the casino, where she bumped into Xiao Yu and Shen Yanzhi... Three entangled emotions were hidden in the daily stitches and fireworks. How should Su Wanqing sort out her inner affairs?
