I remember reading this light novel. The novelty concept is interesting in the beginning, but for me personally, it wore out its welcome after a while. Nothing really changes, the same stuff keeps looping over and over, the only difference is where it happens and involved parties.
By the time I dropped it, there still hadn't been a confrontation or a change in the repetitive pattern. So all the good ideas were used up in the start, and the author is trying to stretch it forever.
