FL diguises herself as her twin brother to save her family from being killed. In the story her borther Celestine served the villain and was killed after a murder attempt on the ML along with his family. Selena took over that role and tries not to attract attention but is still noticed by the villain of the story. She realizes that the villain may not be as evil as she thought and that the story differently than when she read it. One of the best stories I've read up till now.
