Book: Little Woman

I finished reading this book called "Little Woman"(pic).

This book is about one poor family. There are 4 sisters: Meg, Jo, Beth, and Amy. Their father is far away because he has to fight in the war.
In this book Jo found one boy named Lousia. They became really good friends. Beth got scarlet fever because she took care of her friend, but she cured well. Meg married her father's friend!
I like love story so I like that pretty much but I expected that Jo and Louisa become boy friend and girl friend! My friend told me that there is movie of this book so maybe I should watch it.
