After I died in an accident, I entered the body of Yurina, the female antagonist who would later be killed by the male supporting character in a novel. I just lived my life as Yurina while remembering the contents of the novel and looking for ways to survive. But... "Remember, Yurina. The only person who can save and kill you is me. So you have to be by my side." I actually made the male supporting actor become obsessive.
