After I Mistakenly Became Pregnant with the Prince's Son, My Two Late Husbands Who Died in Battle All Came Back.

Are There Any Novels About Two Girls Who Don't Attack or Counter-Attack Each Other?

I really need it so much. I used to have a book that I really loved, but! At the end it actually turned out the other way! It's so sad. Why do the two girls basically love each other?
