Yes, they better make it quick if it's the route they're going. Am thinking of letting this marinate for a year at least if that is so to avoid dying from frustrations
Someone said that in the novel the sister did try to impersonate her, but by that time both the ML and FL had already figured things out, so obviously the ML never believed the sister.
I am dreading the next part. I hope they don't go the route of ML mistaking FL with her sister. Or if they do, I hope it's not long.
