this is so sweet omg i’m so sorry for getting around to it so late 😭 obviously her character stories and companion mission are must reads so i recommend becoming familiar with those and i’d also suggest revisiting her section of the “foxian tale of the haunted” event. as for readables “an exchange diary between pilots” is crucial to understanding her character and her history and the past and future lc description is brief but provides more insight to her perspective. you can read her character introduction here (https://www.hoyolab.com/article/19583612) and it’s partly reworded sections of her character stories but it’s worth looking at. i’d also recommend her text messages and parlor car dialogue!
