I just finished reading through Chapter 11. It's a very comfortable read and works hard to show how comfortable the girls are with each other. I really enjoyed the scenarios presented in various chapters, but there is one thing that surprises me. After eleven whole chapters, there is virtually no indication that this anything more than cute platonic Elsanna. I really don't see any indication that this headed towards a romatic conclusion. If it is, then it may be the slowest burn romance I've read in a long time.
Regardless, the story is well written. You capture various character traits really well and may be the first author to ever suggest that as composed as Elsa is as Queen that she is actually a slob in the bathroom. Hilarious!
