Tired of the hustle and bustle of the city, Lin Xi resolutely returned to his hometown, determined to revitalize the dilapidated old teahouse in his childhood memories, the "Ming Xin" blueprint. However, he encountered sharp criticism from Shen Yan, the patron saint of ancient buildings. When ideas collide, sparks fly - she pursues innovation and leads to traffic, while he sticks to the bones of history. From the scrapping of brick walls to the repair of wooden beams, there are constant disputes, but they are also overcome side by side. Budget overruns, neighborhood disturbances, sudden rainstorms, and the temptation of capital are present. Lin Xi refuses to deviate from the original intention, and Shen Yan silently protects the ingenuity. In guarding this small building that carries time, the two rivals who never gave in to each other gradually became comrades who appreciated each other and had the same mind. When the transformation was first completed, the fragrance of tea was lingering, and an equal love that sprouted in the collision of tradition and modernity and grew in side-by-side struggle was quietly blooming.
