Thank goodness, MC's personality and temper isn't like HYX. To all those who like HYX, no offense, but I personally think she isn't suited for this palace schemes and dramas. She was too soft hearted for my liking and easily driven by emotions. I also disliked author describing her as calm and noble at times. In my opinion, HYX,'s temper and bearings were nothing out of ordinary. At most, she was confident of her poison skills and I found that respectable. As for other things... She only had bits of smarts.
On the contrary, I like Yan'er. She is smart, clever, calm and rationale. Unlike her Mother whose heart would soften at the sight of children, Yan'er would pity them, yes, but wouldn't change her plans for them. She was more calm and composed when dealing with things. And, when ML 'betrays' her, she's mentally hurt and suffers, but she pulls herself together and doesn't act as if the world has come to an end.
Honestly, I felt that Yan'er was more of a woman from modern times than HYX.
