Honestly, the story is anxiety inducing for me. The false identity, the lies, the acting, it makes me nauseous. As the summary explicitly states the real Charlotte will be coming back as well, reading it just makes me a bundle of raw nerves so I can't exactly continue. "Will he find out?" He found out in the first few chapters that she wasn't who she was pretending to be, there's no question. That's not even a spoiler, it happens so fast. Obviously, though, considering it was the woman he loved acting completely different all of a sudden.
That said, it's interesting. Just too stressful for my weak self, lol. I hope they find their happily ever after, but any story that builds off of lies and secrets in this manner, I just can't read them.
