I'm Thinking of Quitting the Villainess' Entourage

Diet... to avoid the Bad End! In a former life, Cosette was just a normal housewife. Now she’s been reborn into the world of an otome game, not as the heroine, or even the villainess, but as a chubby unnamed NPC?! Is she destined to be pushed aside as the heroine follows her route, or can Cosette avoid the dark future that awaits her?
