I understand your concern, and honestly since we’re dealing with a time loop and time control here, there really wasn’t any info on how they truly met w/o time loop (since it wasn’t delved in), it really has to come from the author about this. As long as there’s a time loop kinda thing in the story, this “plot hole” is bound to happen
I understand what you mean but at this stage when my brain starts to think about time loops or the timelines I go
Mehhhhh that's enough ╮(￣▽￣)╭ and just don't think about it. Otherwise it is bound to find some plot holes or some existential dilemmmas
Now we know that she met Kasar cause she wanted to know more about him and that was the start of his devotion for her but one thing I still can't figure out is how they truly met, because there should be a first timeline where they met (a Kasar without Seul of the future as his master) and all the shit went down and she defeated her mother and then she went to meet Kasar (the kid Kasar that will grow up to be current Kasar)
And then the story repeated itself and she once again went back in time.
So basically the pre-timeline before present loop-timeline
I'm not sure if I explained myself well enough for people to understand
