The little fox fairy who inadvertently walked out of the Fox Lord's green screen formation in the Fox Fairy Valley was wandering around the world. A mysterious mortal accidentally used a soul-locking nail to restrain his life gate. Under his coercion, the little fox fairy had to follow his request and complete his mission. The first thing he asked her to do was to marry into a powerful family to obtain the secrets hidden in this family. The second thing he asked her to do was to leave the person she fell in love with. The third thing he asked her to do was to forget him forever. When all the layers of fog were peeled away, when the life experiences of the two people were revealed, they discovered that it was all just a joke from God. There are many misunderstandings and deep love. After three lives, who will fall in love with whom?
