Alps Monogatari: Watashi no Annette

アルプス物語　わたしのアンネット

Annette was born into a poor family in Switzerland.

She is a sweet girl and takes good care of her little brother Dannie. Lucien is her best friend.

One day Dannie gets injured and develops a limp. The accident was Lucien's fault.

The happy days turn into a long period of suffering, but little by little Annette and Lucien regain their lost friendship.
