Spoilers
As of now, two timelines but there are actually three. Season 2 and 3 I think are the second timeline with Aeroc remembering the first. Third timeline is with Klopp remembering the first timeline. Basically the spirits/souls of the Aeroc and Klopp in the first timeline are in two different timelines. They didn't meet again, if I remember the spoilers I've read correctly.
As far as I've read the novel , I found no 3rd timeline. Just 2 timelines. This current one will be the last.
It was long back I read it. Bcz i just couldn't wait for the story. It was breaking my heart.
Im so confused so I decided to read the comments but now im hearing there are different timelines? WHATS GOING ONNN
