Lin Jianying, the proprietress of a braised food stall in a night market, formed a "liangzi" with Gu Song, a cold-faced lawyer from the law firm next door, due to road management issues. They thought it was a neighborly relationship that did not interfere with each other, but it gradually turned sour due to Gu Song's frequent visits to the stall. From complaining that the braised food was too fragrant and affecting him from working overtime, to secretly helping her drive away the drunkards who were looking for trouble; from pretending to be serious and pointing out the legal loopholes in her "not issuing invoices", to silently remembering the placement habits of items in each of her stalls - the two of them interacted with each other amidst the fumes of fireworks. To heal, Gu Song wrote a romantic love letter like a legal document, and Lin Jianying taught him the "seasoning of life" with the secret recipe of braised food. Finally, at the celebration banquet of the upgraded night market, Gu Song proposed to her with customized braised duck wings, creating a fireworks love from mutual hostility to sweet love.
