The real world doesn't become fantasy-like like you're wanting, but they do heavily affect each other. Grid starts out as a worthless, money-obsessed little shit who is utterly hateful, spiteful, and stupid (I think they've skipped over his numerous deaths to bunnies and shit). Though they seem to be glossing over his innate toxicity in this adaptation, thankfully. It's so bad that there was a toxicity warning on the novel. BUT. Grid is perhaps the character who shows the most steady positive character development I've ever seen as he goes from a have-not to what Satisfy ends up making him. (He starts getting better around chapter 90-120 in the novel, and it's all uphill from there.) Novel's one of the most popular I've ever seen, and these days everyone has nothing but love and praise for it.
