Huaiyue was the most cherished princess of the Cangwu Kingdom, yet on her wedding day, she was stabbed to death by the man she loved, Wuji. Reborn with her memories intact as A Xiao, a farmer's daughter, she swore to avenge her previous life's death. When she turned eighteen, Wuji appeared before her again, mysteriously unchanged in appearance. A Xiao pretended to accept his affection while secretly plotting revenge in the same way: to kill him with her own hands at their wedding. However, as they spent time together, A Xiao discovered that she was falling for him again, while Wuji seemed to be hiding a secret of his own.
