Sora o Daite Oyasumi
This is a wonderful although extremely sad and tragic story. The one twin is so lost and confused,I cried so hard at some points. I really do hope that there will be more to this story in the future. If you read this make sure you have a box of tissues by your side, you will need them.
Yoru To Asa No Uta
The two main players in this are wonderful, I feel so bad for both of them. This is a pretty good story, may read again sometime.
