The lively and lovely Chen Shuangyan (played by Cao Xiwen) met the handsome Lin Yifan (played by Guo Xiaodong), and the two who were in love finally decided to join hands in marriage. Although the mother-in-law (played by Pan Hong) was very satisfied with Lin Yifan's conditions in all aspects, the fact that Lin Yifan had a marriage history made her unable to truly accept her son-in-law, so the relationship between the two was actually very tense. After learning that her ex-husband had remarried, Lin Yifan's ex-wife Yang Fangfang (played by Chen Yanfei) began to think crookedly. In the name of her daughter visiting her grandmother, Yang Fangfang began to appear frequently in front of Lin Yifan's mother, relying on a three-inch tongue to coax the former mother-in-law into a trance, making Lin Yifan more and more dissatisfied with his current daughter-in-law. Under internal and external attacks, the marriage between Chen Shuangyan and Lin Yifan began to become precarious.
