I don't know how you want to understand it, but the truth is that the owner of this account has changed.
I am Xiaoyuan.
Twilight is my real life friend. Or someone I know is more relevant.
This account is just for me to write novels. Now I want to tell the story of my sister Yueyue. Most of it is made up, with her as the protagonist of the novel. She is neither my classmate nor my biological sister.
