An accident took away the life of Gu Yanzhi, the eldest brother of the Gu family, leaving his young wife Shen Zhiyi to face the infighting of the wealthy family alone. At the funeral, the brother-in-law Gu Xingzhou, who had been wandering away all year round and was regarded by everyone as the "prodigal son", suddenly returned. Everyone thought he just came back to attend the funeral, but they didn't know that what he was waiting for was the moment when his eldest brother died.
Three years ago, when Gu Xingzhou left, Shen Zhiyi had just married into the Gu family. When he saw her for the first time at the wedding, he knew that this was the fate of his life. Now, he could finally stand in front of her openly and invade her life inch by inch as a "family member".
What Shen Zhiyi didn't know was that Gu Yanzhi's death might not have been an accident.
