Inori no Orihime wa Koi wo Suru ~Kiraware Reijou no Migawari ni Nattara, Konyakusha ga Hatsukoi no Koutaishi-sama Deshita~

Marie works at a tailor shop run by a brothel, where she is a highly sought-after seamstress affectionately known as the "Weaver Princess." However, her peaceful days are shattered when the brothel owner suddenly orders her to become the exclusive courtesan for a wealthy merchant's son.

Just as Marie falls into absolute despair, a beautiful, masculine-dressing noblewoman named Emma appears before her with a shocking proposition. Emma wants Marie to act as a body double for her runaway younger sister, Maria, whom Marie happens to resemble exactly! The goal? To deceive Maria's fiancé, Prince Carlo, and make him despise her enough to annul their engagement.

After much hesitation, Marie accepts the deal. She is swiftly educated in the elegant ways of a count's daughter and begins attending the same academy as Carlo, masquerading as Maria. But there is a massive catch: Carlo is actually Marie's first love, a boy she met only once ten long years ago!

She is supposed to be doing everything in her power to make him hate her, so why is the prince treating her sweeter and sweeter by the day!?
