Im not sure if you read the Novel but there's another side story about that..
Spoiler warning kinda???
There's another side story where Aeroc does wake up after what happened to him in the first timeline. He wakes up and Kloff finally realized what he was doing was wrong and forgave him. That day he meets all of his children and finally can be their parent. They move out of the estate and very slowly start moving forward.
Its a really bittersweet ending, because everything that Kloff did still exists and Aeroc is still affected by everything he had done so far.
But didn’t aeroc die with his the birth of his sixth child though
The saddest part of all this is that aeroc never got to meet his 1st timeline kids and know their name, how they grew up, what they grew up to be, if his children ever misses them and later resents their father for killing their mother, the fact that he’ll never know that his eldest son left the home he grew up in because he associates it with the suffering of his father/papa/mother and be rather called aeroc.
The fact that he even longed to see them in his 2nd lifetime but couldn’t
