She was once the star performer of the century-old opera troupe Swallows Return, but after losing her memory, she was mistaken for the missing eldest daughter of the Shen family. He married her and treated her with tenderness, unaware that her secret investigation into the old case that wiped out her family was pushing him toward ruin.
He thought she was a pawn in a substitute marriage, while she thought he was descended from her enemies. But when layer upon layer of deception was stripped away, the truth proved more absurd than any opera: she wasn't a Shen daughter, and he wasn't the son of her enemy. Fate put them in the wrong places, then brought them together again on the opera stage. As the drums and gongs sound, who is playing whom?
