A scheming younger sidekick x a spoiled, haughty heiress.
Shen Qingyu has been in the world of a novel for two years without even realizing it. All this time, she's treated herself as a mere onlooker, quietly following Liu Jiashan, the villainous heiress in the story.
Until one day, a desperate phone call from Liu Jiashan changes their relationship in subtle ways.
After that, Shen Qingyu is always hearing Liu Jiashan's soft, almost coquettish little hums.
Gradually, she realizes she can't bear to watch Liu Jiashan fall for someone else, or to see her meet the fatal ending written for her.
Liu Jiashan grows more and more domineering toward her, forbidding her to leave and refusing to let anyone else near her. She even bites Shen Qingyu's lips while saying she hates her...
Later, Liu Jiashan makes an unreasonable demand: she wants Shen Qingyu to be Lu Xiwen's substitute.
But... apart from both being women, she and Lu Xiwen look absolutely nothing alike!!!
