[Pride and Prejudice] Lydia's Comeback

After transmigrating into a book, she discovers that she has become Lydia from Pride and Prejudice. The shallow, ignorant, foolish, and frivolous youngest Bennet daughter. Worse still, the moment she arrives, she is running away with Wickham. Her bad reputation has already spread throughout the entire family. How could she let that stand? So she does three things: gets rid of the loathsome Wickham, rescues her reputation from rock bottom, and sheds her shallow, ignorant image. All three sound difficult, but somehow she succeeds? And somehow, using her own brains, she even becomes the darling of Longbourn village? P.S.: 1. No breaking up couples, no character assassination, no OOC. 2. The writing style stays true to the original. Theme: Intelligence is essential.
