I have always felt that Ziwei's character was that of a typical lady in ancient times, as handsome as Fulkan. What kind of daughter has I never seen? Qing'er is the best example.
Little Yanzi is different. She is not bound by any ethics. She is capable of cheating and abduction, but she is kind and cute.
Erkang is much more rational and calm than Yongqi. Except for his identity, we don't differ from him in anything.
So I'm curious what would happen if they fell in love?
