Author’s review here. It’s a five star for me. Personally I feel like it’s a wonderful concept and a different system from what we all know. The System in this novel is an AI which ended up developing feelings and self awareness outside of its programme, so it struggles to take over the MC. The MC has to struggle between his dreams and a system he had later come to regard as a friend. Really, try it. You’ll love it, I’m sure of that.
