Lol just deduction. The fact chloe is taking a potion to stay looking like a female, plus all of blaises dreams and other clues just add up. The reason why the original chloe was never happy with the mls is cuz he was a straight male... Hence why (probably) the author discontinued it bc they may not have know how to resolve the issue they made. Its not certain but I'm pretty sure that's what happens
It was actually kinda obvious since it was already mentioned that the original story was unfinished and that the FL mentioned that the original story didn't mention about chloe's feelings even once about her suitors or anything in particular. It was also revealed in this timeline that Chloe is actually a man and that he's only drinking some potion to keep them from finding out what his gender truly is. The story's not complete so the readers never knew that Chloe is actually a man in the original story.
so.. the lady and the hound chloe was the protagonist...but she's a man.. what is going awn chile my head hurtin just from thinking about it messy
