Are you talking about r9kElsa ? I'm not the author so I can't really answer but I don't see any reason for the chapter 40 to be the last :/ You should ask directly to the author
Yes, the fic r9kElsa, I know who the author is, but I thought you knew something about it, the truth is that it is very good, you're right'm going to ask directly to the author, thanks for replying to my post and sorry to bother you, thanks
