Two souls in one

This is a story I wrote myself. This is not fanmade or anything. It's a story that I came up with on my own. There's a girl by the name of Rena Rose or Rose Gen. Rena Rose is from a different part of the universe and Rose Gen is from another part of the universe. But the question always bugged her. Who was Rena Rose? Why did everyone say that she was Rena Rose when she was only Rose Gen in her ponit of view. Read the book to find out who Rena Rose and how Rose Gen is.
