The Fake Hero Defeated the Real Hero

I was living an ordinary life while reading a novel. As usual, I fell asleep in bed and when I opened my eyes, I found myself possessed by a fake hero from the novel I was reading. And a villain who would make the real hero shine someday. Since I personally admired heroes, I planned to act as best as I could and leave as a villain. But somehow, I defeated the real hero and became admired as a true hero. "Someday... I will reveal the truth." Plus, I received resentment and strong hostility from the real hero. ...What should I do?
