My wittle heart hurts! XD I loved this!

I loved your story! Mainly because I feel it so in character and it so well written. I liked a lot that this was centered around the fact that Wanda is still mourning Pietro (I was really disappointed it didn't got a descent mention in civil war). The idea of the four rules is brilliant, I think it embraces the similarity in their personalities in a way that it just makes sense that they (the rules) exist between them and also it represents a safe way in which they can help and support each other.
I conclusion congratulations and thank you for writing it!

This was actually beautiful. Sometimes there are too many happy endings and people don't realize that life is about the anger and sorrow as well, sometimes moreso.
Well done.
