I usually have better luck with reincarnation stories, but from what I've read of the novel (about 50 chapters of the 150-chapter story) this is just an absurdist fantasy. It's not even a romance, it's just that the two main characters happen to be married.
Don't ask me what the plot is supposed to be: I think we're supposed to uncover the reason for why magical knowledge has decreased so drastically over the past 500 years. I don't know. ╮( ̄▽ ̄)╭
