This is a harem novel about a guy trying to save the world by writing a harem novel. I tend to dislike any hint of breaking the fourth wall, so I thought this approach was a turn off instead of being clever. (I also didn’t care for the business names “McStarbucks,” “WalMacy’s”, “eBaymazon” etc.)
I will say, the idea of the MC asking a friend for advice about his real situation by describing it as a story and asking for narrative advice was kind of interesting, but that was the only aspect of it I liked.
