@Ibbx Sorry if my English isn't good. From what I understood from a previous explanation "Spoiler" Amon is a dragon, and Na-in is like a human linked to Amon, which allows him to regenerate. So in In his previous life, Amon swallowed Na-in, who took it very badly; in this life, Amon, through all their murder ceremonies, is trying to prepare Na-in for death. But Na-in simply dreams of a sweet and peaceful life without complications; these memories of her previous life are continually erased through the incense ceremony to prevent her from to flee or to fear one's fate
