The drama is adapted from the xianxia novel "One Moment of Impulsiveness, Seven Lives of Unluckiness," which tells the story of Xiang Yun, a fairy of the Moon Elder Pavilion, and Chou Kong, a disciple of the Star King of Mouri, who were sent down to the mortal world by the Jade Emperor to experience seven lifetimes of love. Xiang Yun was originally a cloud, but was later transformed into a fairy by the Moon God and worked in the Moon God's Court. The two of them quarreled and accidentally messed up the red rope, leading to a marriage chaos in the three worlds. The Jade Emperor found out about it and punished them both for going through seven lives of love before they could return to the heavenly realm, and the story began from there.
