I thought, given these two people, that this was an excellent story and I rather suspect that if/when you muses pushes for a sequel that a lot of things are going to get *very* interesting and lively. If Hermione returns home and salvages that letter, it's definitely going to dsitribute fecal material over a wide range.
It may be fluffy, but it's quite believable. I daresay Ron is going to be quite surprised when she changes every lock and access and kicks his cheating ass to the curb as she moves on, and in, with Harry on a permanent basis. I wonder who will screech louder, Ron, Molly, or a still-delusional Ginny?
