Yes it’s an AU/side story. Kloff remembers timeline 1 while Aeroc doesn’t. I haven’t finished it yet (because the one translation I found only got about half way so if anyone has a full translation PLEASE I BEG) and it’s pretty interesting, especially seeing Kloff in agony for what he did and Aeroc finally having some reprieve from his last lives.
You wouldn't want to read that time line its traumatizing for real, he try to kill aeroc
Novel updates has it
He wasn’t in his right mind when he did that, so I don’t think it’s fair to say, “He tried to kill Aeroc.”
He hid himself in his house during his rut period, and he was clearly in agony. His past and present were mixing together, he had overdosed on medicine, and he was suffering badly. Aeroc didn’t know the full situation and went to his house without realizing what state he was in.
Wasn't the other timeline where kloff only remembered on here? I swear I thought I read a few chapters of that.
