In the middle of reading I thought that this idea of 'trying out' different girls (who may or may not remember things between loops) like some kinda playboy is only good for causing heartbreaks for everyone involved.
Of course the author was one step ahead and things got more screwed up than I could imagine.
So he died or is comatose (prev chapter the other girl had a hospital scene flashback) and she wished for him to come back/whatever happened to never have happened, hence the loops so that it won't lead to that future?
but it is still accepting her wishes? is it her power? or is it because the changes are against the original wish, hence the reset.
