Before you read this review bear in mind that i read the spin-off " Saenai Heroine no Sodatekata: Egoistic-Lily" first before i read this one. (Also there will be some spoilers in this review.)
Story: it's interesting how in the spin-off aki forms a doujin circle and how in this one he becomes the editor of kasumigaoka. The story of this manga kinda reminded me of the anime "shirobako" because of the part of the story when one of kasumigaoka's light novels was planned on being adapted to an anime (not gonna say which one to decrease spoilers.).
Art: it's as good as the spin-off's art. (No complaints here)
