The feud between Qingxuan and Shen Mansion is confusing in the eyes of a group of girls. A chance encounter in a teahouse, an inexplicable play, a set of soft jade porcelain cups, a bewildered man... Everything makes the incident point to a situation that they cannot predict. They can't guess the dangers of the rivers and lakes, and they can't guess the ending and origin of fate. They can only wade in the cold and dangerous undercurrents and move forward with difficulty, but they unknowingly change everything.
