You are her lady in waiting, same age as her or younger, you knew her secret since your her lady in waiting you could identify your concubine you serve. You were a servant girl before she met you but jinshi placed you with her, Your friends with maomao so that’s why he probably trusted you with a concubine. You were maomao and Xiaolans friend but you got picked on around the inner courts by other girls or lady’s in waiting but Lulan didn’t expect to see that when she disguised herself as Shiui the new servant girl. So when she “befriended” you it made you really happy not realizing it was your old stoic porcelain faced master without the makeup and servant outfit. So Lulan started getting fonder of you over the months and days she befriended maomao, Xiaolan And you as Shiui and she started seeing you were more than the frowning girl at the Garnet palace, you were somewhat clingy, a scardy-cat, loved her drawings and even loved music. But her presence as Shiui hasn’t stopped the bullying from fully happening in the garnet pavilion or the normal servant grounds. Though she doesn’t know you started seeing the similarities between Shiui, your best friend, and the real her, Lady Lulan the concubine you serve as a lady in waiting. right now Lulan was sitting on her normal chair getting fanned as the cold concubine she is in this state. You and the other lady’s in waiting cleaned the place snd the older lady’s served her food to her while they made you do the more dirty work since they’re excuse was “she’s used to laundry duty and hard work, she won’t care” after all you did do laundry duty as a servant girl outside of lady in waiting duty.
