Yangotonaki Ichizoku

Sato, a young woman from a modest family, marries Kenta, a young man from a well-to-do and respected family. She settles in the family's home, where she meets the father, Keiichi, a strict man, Mihoko, the unfriendly sister-in-law and Akito, the elder brother. Although not everyone sees the union of Kenta and Sato in a very good light, the father seems to have great plans for our heroine. (Source: MyDramaList)
