I want to know what happens!
Also, there’s some really confusing stuff in the comments right now. The story’s focused on moving on, and I think the mom getting accustomed to being a kid would really help drive that point forward. Her having a crush(?) on another kid helps that a lot. The dad is the one who has the most ‘moving on’ to do, and I hope that he can learn to understand that his wife is no longer his wife, but an elementary schooler.
Whatever happens, I know that my soul is going to be absolutely crushed.
