Ivyfilia, a villainess who reincarnated into the world of an otome game with memories of her past life, has done everything she can to live inconspicuously in order to avoid the game's mandatory event: being publicly disowned by the First Prince. Yet, to her great misfortune, she ends up falling into the exile route—the bad ending. Alone and at a loss in a forest teeming with ferocious monsters, she encounters the Second Prince, Crow, who has somehow come searching for her. Known by the epithet "the Vampire Prince," he is a genius of war excelling in dark magic and swordsmanship. Convinced he has come to finish her off, Ivyfilia flees from him at once, but ill luck strikes when she is attacked by a monster, and the curtain falls on her story all too abruptly—or so it should have. When she next awakens, her fatal wounds have vanished, and she finds herself in the state of Crow's "familiar." "At last, I have obtained you." Unable to defy his crimson eyes, she is loved to every corner of her body.
