While I loved the Submissive Sadistic Power Bottom and Dominant Masochistic Slightly Submissive Top dynamic, there was not much background info given about the world around them and the climax being about familial trauma resolved with an apology after so many years and the severity of what was done really lowered the quality of the story. If that portion was removed, the story would be the same so it was essentially a waste of pages.
