For those who read the novel, can you guys tell me what happened in the third timeline?

from what the spoilers I've seen about it, it's basically Kloff eating shit. This time it's him who remembers everthing while Aeroc is none the wiser.
They still end up together but it's this thing where he's stuck in his past memories and regret, and can't truly love that timeline's Aeroc bc of that. Someone will correct me if I misremembered it.
