Just after Meng Chuli got the deed to her new home, a torrential downpour began on her way back. She transmigrated into a book as the villainess, the Princess of Nanping. She tries her best to follow the original plot, complete her mission, and return to her own world. Right from the start, she mistreats the tragic, handsome antagonist, but ends up unwittingly flirting with him. She never expected him to be so hopelessly in love, and as the plot slips further out of control, she finds herself drawn into it too.
