Country Love 17 continues to spotlight the lives of the villagers in Xiangya Mountain, with a special focus on the marital crises of several young couples. After recovering from a stroke, Liu Neng witnesses a series of family, marriage, and emotional upheavals in the village. To help Hong Xu with financial troubles, Liu Ying transfers her flower nursery to Shunzi, triggering dissatisfaction and conflict with her husband, Zhao Yutian. Meanwhile, Song Xiaofeng's overwork managing his Airbnb strains his relationship with his wife, Song Qinglian. Other couples, such as Wang Xiaomeng and Xie Yongqiang, and Bai Qingming and Li Yinping, also face their own relationship struggles. Village official Du Xiaoshuang announces a province-wide"Most Beautiful Family" competition, sparking enthusiasm among the villagers. In response, Liu Neng creates the"Xiangya Mountain Fathers-in-Law Alliance" to rescue the struggling marriages of the younger generation, while his rival, Xie Guangkun, counters with his own"Xie Guangkun Team." Though both aim for the same goal, their efforts are hilariously chaotic.
