Before I keep on reading. Is the FL also a person who transmigrated?

Yes -- that's the plot of the story he's found himself it as far as he knows it. The story, as he knows it, is about a FL who is transmigrated into a novel she was reading and living the events. Raises the question if she's from the same world as Jesse or is herself a fictional character who believes herself to be real.
