Qingyuan and Li Xiaofu are sweethearts. Because Shuangshuang and his parents came out as gay, the two parents were worried. Based on the mentality that giving their son to someone they don't know as a boyfriend is not as good as giving their son to a comrade's son as a daughter-in-law, Li Xiaofu was sent to Qingyuan's house to become his wife. This begins the story of getting married first, then falling in love.
