Reincarnated in Another World to Become the Heroine of a Doujin Ero Game!?

A young woman finds herself reborn in the world of a doujin erotic game, but not as the protagonist or a side character—she becomes the very heroine whose role is to be the target of the game's explicit scenarios. Armed with nothing but her own body, particularly her prominent chest, she must navigate this new reality where every encounter seems to push her toward the game's predetermined events.

As she struggles to adapt to her new life, she realizes that her knowledge of the game's plot might be her only advantage. However, the world operates on rules far more lewd and unforgiving than she ever imagined, and her attempts to avoid the game's narrative only seem to draw more attention to herself. With her only dependable asset being her own curves, she must figure out how to survive—or embrace the fate that awaits her.
