Song Qi, a struggling online novelist, had just finished reading a hit wuxia novel called Tianxing (Star of Heaven). She was filled with unresolved grievances. For the sake of the beautiful but tragic villain, she wrote a ten-thousand-word commentary—more diligently than she ever wrote her own stories.That very night, heartbroken over the villain's death, she felt a sharp pain in her chest—and then she transmigrated. She found herself inside the world of Tianxing, inexplicably becoming the male lead’s younger sister, who shared the exact same name as her.Fine, she thought. But this sister in the original novel was good for nothing—all talk and no action. To be honest, that description fit Song Qi perfectly. It wasn’t just similar; it was basically her.Just as she was cursing under her breath, an electronic voice rang out:“Song Qi, I am System Hutu No. 2. Your mission is to change the villain’s ending. Complete it, and you can return to your real world.”Song Qi: “Wait—you mean change the ending of my dark love (the villain)?”Hutu No. 2: “Yes.”Song Qi: “But she’s already turned dark!”Hutu No. 2: “…Oh no. I set the wrong timeline. I sent you to this point by mistake.”
