I feel really sorry to the first Ruqing, simply because for all bad she did she actually just misguided naive kid. She could have been a good kid. Rushuang is super oblivious and faking her obsequious persona for so long. Dai'er have mentality of a child but she is more sensitive to malice, she realize early on for all meanness of previous Ruqing displayed, Rushuang is the real villain.
