In my opinion, I don’t think it BS at all! It base on the novel and I find it interesting that it divulged in a “what if” scenario where each person return to the past with memories of the first timeline and see how the story change/what they did differently knowing the future
The main story is already over. This one is just a side story and you can skip it. First life Aeroc gets his happy ending meanwhile first life Kloff gets his punishment, I think that's fair and not bull at all ! And I did not mean to upvote your comment
I hate when authors continue a story just to add some bull
