Marriage in one life, love in two lives, and agreement in three lives. He is the holy beast of the snow-covered plateau; she is the daughter of an insider and outsider in Youzhou City.
He made an agreement with her that he would only protect her and be loyal to her for three lifetimes. He would only protect her from rebirth for three lifetimes and die just for protecting her.
Is it just for an agreement between master and servant or for her whom he cares about the most?
Three lives and three lives, I am just your dog.
