Akuyaku Reijou no Torimaki Yameyou to Omoimasu

In the kingdom of Artoria, a popular romance game centers around a competition for the crown prince's consort. Cosette, a housewife reborn into this world, does not take the role of a hero or rival, but instead appears as a minor background character. Without action, she faces an inevitable bad ending. As she becomes entangled in the political maneuverings of the aristocracy, she also grows closer to the crown prince.
