The story begins when Wang Baochuan dies of illness in her humble cave dwelling. Before her soul can fade, it collides and merges in a violent temporal maelstrom with the soul of Su Xiao, who has transmigrated here by accident. In the end, a “new Wang Baochuan,” with the memories of two lifetimes, both emotional and rational, both fragile and strong, awakens three days before the ball-throwing ceremony where she must choose a husband.
