I think they are both. “Manufactured stories of love” are like the poems, novels and plays you can write at Court: they may be well liked by the Empress and her courtiers, but won’t interest the Bazaar in the least. “stories of manufactured love” would be more like the Princess/Sculptor story cited by Urthdigger: true stories about fake loves, and they aren’t liked by the Bazaar either. You want to appease the Bazaar, you need a true story about a true love ^^
