I’m sorry but who is violet??? Someone explain please

Back in the past, Violet was WangZi's fren who got kicked out of the loong ranking due to xiao fan taking the slot instead

She's wangzi girl bff. They're treat e/o like real sibs. But violet got sent to human world because of fan fan using his family's connection to get the 10th spot. That's why Wangzi hated fanfan so much before.
