I Reincarnated as the Villain in a Romance Game I Mastered, So I'll Conquer the Heroine Using My Knowledge of the Original Work.

I, Yuuto Hatano, love the bishoujo game "Houkago no Flare Story" and have played it over and over again. I thought, "If the world were like this, going to school would be fun..." Then, when I woke up the next day… I had entered the game world! And not as the protagonist, but as the villain, Kanji Aku! I had hoped to do all sorts of things with the heroines I admired, but as a villain, their affection for me was at rock bottom. With this, conquering them is nothing but a dream within a dream... Moreover, if I choose the wrong option, what awaits me is death!! As a villain with the lowest stats and lowest affection level, I must overcome deadly choices, conquer the heroines, and escape this world—Go, Kanji Aku!
