If they all can just loop back and get the wish again and again, why can't he just keep looping and get stronger to one-shot the demon lord before that original hero develops any attachments or better yet, just use his wish to transport him back to his world without any memories of this world...now this novel just keeps hurting my brain, i know its my fault for bringing logic into a hentai esque novel, but still author shouldn't challenge the brains of its readers that much ¯\_(ツ)_/¯
Shhhh~
