The Tyrant Brother Is a Bonus

I struck it rich with a coin investment—then died in a plane crash the next moment.

When I woke up, I was inside a novel… as the villainous noble lady in a dark reverse harem.

If I keep my engagement for one year, I can return to my world—right to the day I made billions.

Easy, right?

Nope.

My fiancé despises me and wants out immediately. My tyrant brother—the male lead—keeps sabotaging me at every turn.

Now I just have to survive one year… and make it back to my fortune.
