The Blood of the Crown [BL]

I reincarnated into a novel alongside my sister, but with an unexpected twist: I became the villain destined to ruin the male protagonist's life. Instead of resisting my fate, why not embrace it? If I’m to be the villain, I’ll use every skill at my disposal to take him down from the throne and claim the title of the next emperor. After all, in this new life, I make the rules.
