On the day of his mother's funeral, Lin Zhaowan was picked up by the Shen family in Beijing and became the real daughter of a wealthy family twenty years late. She refused to change her surname and refuse to be a pawn at the mercy of others, but she was forced to get involved in a marriage based on a spring banquet. The frail heir Xie Tingyun is gentle and distant, but reaches out to her when old scores and murders come to light. The Shen family is as prosperous as a dream, and the Xie family is undercurrent. She wakes up step by step between family ties, engagements, and old cases, tearing apart the truth behind the feast with her own hands, and saving herself from the arranged life.
