*****Author's note: For readers who are confused with the new volume. This is Zenith's first life. As you can see, it's about rebirth. The reason why Zenith felt this strong regret for Dawn and why he seemed to know her even when they just met. The previous volume is about his second chance life. He turned back time to correct all the mistakes he had made.
And in this volume, it's about his first life from Dawn's perspective. Dawn got to see what actually happened in his first life after Zenith marked her after the royal ceremony.
Hope it helps.*******
==================================
Dawn spent most of her time with her son. Her relationship with Zenith didn't get better, but it didn't turn worse either. They simply lived in two different worlds.
