I wouldn‘t ve surprised if the hero himself gets reincarnated time and time again as well. And he always remembers what he did to his first lover like she does.
It was quite a nice read, but so short I guess it was axed.
The plot progression was kinda bad (who the hell explains their moves on the battlefield. Sure, it was a "chess game" but still, it's live or death) but otherwise the art was to my liking
