If everyone had a character card with a maximum score of 100,
then Lu Jia would be a useless card.
In terms of status, Lu Jia is the legitimate daughter of Prince Kang's household. She can't punch the legitimate daughters or kick her stepmothers, so her score is -10.
In terms of talents, Lu Jia excels at eating, drinking, whoring, and gambling. She has no chance of mastering music, chess, calligraphy, painting, or the performing arts, so her score is -10.
In terms of her name, Lu Jia is utterly ordinary. Her rivals are Shangguan Linglong and Ximen Liuli, so her score drops another -10.
In terms of blood ties, Lu Jia is related within three generations to eligible, high-status marriage prospects like the emperor and princes, so her score drops another -10.
In terms of friends and family, Lu Jia has an educated, refined, gentle, and amiable older half-sister, a clever, composed younger half-sister who excels at everything, and a lively, spirited, adorable young cousin living next door. Her score drops by -100.
Lu Jia: I'm a good-for-nothing, thanks for asking. I'll just sit back and let my older and younger male cousins and my older and younger sisters support me.
A certain man next door peeks around the corner: Count me in.
Theme: An unconventional ancient-style romance heroine's rival.
