I'm really enjoying the story so far and I'm also curious where you'll be going with it.
But you should consider to add a little translation section on the end of each chapter. I'm german so I know what words like "Fräulein" and "Herr" mean, but I'm sure there are enough reader who don't.

I'm so glad you updated! I really like this story! I can't wait to find out what the message was! Please update soon!

This could be interesting... how about updating it?
