How to Save Humanity After Transmigrating into a Villainess Princess?

“What should I do after transmigrating into an R-rated game and becoming its villainess?”
Elashia reincarnated into the game—”Immortal King—The Fall of Elasia.”
As the greatest traitor of the human faction—the tragic princess “Elashia,” if she doesn’t betray humanity, she will unlock as many as hundreds of CGs and death scenarios!
Fate compels her to stand against humanity, or else face death.
But no matter what, Elashia, whose conscience hasn’t been extinguished, could never stand against humanity just to save her own life!
Even if suspected and betrayed, she will never regret it!
She would rather be the one who is hurt than hurt the innocent!
So Elashia plans to live one day at a time.
But as days pass by, the girl’s tragic determination seems to have changed?
Guardian Knight Cecilia: “Your Majesty, it was you who helped me find my original intention and redeemed me.”
Iron Empress Alexandra: “My beloved daughter, bringing you into this world is the most correct thing I’ve done in my life. Because of you, I finally understand what love is.”
Holy Princess Ileina: “Shia, I knew you would come to save me, just like five years ago, you descended by my side like an angel once again.”
Elashia: ?
How is this different from the game?
