Mu Yiyi
Winning this competition, though may be insignificant--and even funny-- to some, means a whole lot to Lin Che because her abilities to be Gu Jingze's woman is being questioned and laughed at. She pushed herself and worked hard above and beyond what is expected of her so she can fight and show these judgemental bullies from Gu Jingze's world that she deserves to be beside him even if she's just practically a nobody to them.
Of course Lu Chuxia doesn't have as much strength as Lin Che as she's a pampered daughter of a rich family.She probably haven't faced hardship like her either.She likes to boast about her skills but she is not assured about her own success against her otherwise she wouldn't be trying to sabotage Lin Che at every turn.
