I recommend 520 Happiness Alley, a modern romance novel about wealthy families. Just like the female protagonist, the female protagonist in the book was reborn and returned to her childhood to protect her family and live a happy life. As the female protagonist grew up, she constantly explored her heart and became the ideal woman. This book also expressed the theme of " leftover women need to be self-reliant and self-respecting in order to grasp their own happy lives." I hope you like my recommendation.
