the.com/open book
A person with no plot twists left to spoil.
means Someone whose thoughts, feelings, and history are plain to read, with nothing hidden or held back.
from A straightforward metaphor: an open book has every page visible, nothing closed off or concealed, unlike a shut volume whose contents you'd have to pry into. The phrase extends that image from literal books to people — in use since at least the 1800s to describe someone easily and fully 'read.'
