Also, if I may speculate, the original author of the story must have cancelled it because they were afraid of the backlash they might receive if they reveal this twist haha...
the author in of the novel maybe wants to add this but got rejected that's why it got axed. it will confuse the readers but for me, it will be nice but it will just look like random if not added in the beginning
I wonder if there was actually hints in the original novel about Chloe or more like Claude being a man. At least the Duke and Dace were very much aware about him being a man from the start.
