Regarding the Matter of Somehow Ending Up Selling Goods While Wearing School Swimwear Over Tights - The Vendor Edition

Furukawa Kei, a student at a certain university, is asked by his childhood friend Shirasawa Kanako to work as a sales clerk for a suspicious circle called the "Layering Club" that was founded within the photography research club. The photo collection sold like hotcakes, but what awaited them afterwards was a photo shoot. ※To be blunt, this is just a novel where two girls in school swimsuits and tights interact with each other, narrated from a first-person perspective.
