Oops, I'm Trapped in My Own Tale!

Lyra Hart wrote the novel and now lives in it, with a system handing her tasks she has to finish if she wants to stay alive. She assumed her own book would be easy ground since she knows the plot. Then Evander Travan, the male lead, turns out to be able to hear what she is thinking, which was never in anything she wrote. She has to complete the tasks without being killed by a story she designed to kill this character. He has to work out what she is, since the voice in his head keeps announcing plot points before they happen and referring to him as a construction. They are married, and every conversation in the house has two conversations running underneath it, hers silent and his pretending not to have heard.
