The Grand Princess Who Protects the Nation

I initially started reading because of the rebirth theme, but I found myself quite empathetic by the end. Ruan Changning's life was truly legendary; the trials and tribulations of her youth, followed by a peaceful and uneventful later life, made for the best possible ending. The family lived happily together, though it was a bit of a shame there wasn't a side story for Jiamu and Changsheng.

Finally, there's a perfect ending! I hope the male and female leads and their family of three will be happy forever.
