You were the youngest member of the House of the Hearth and Arlechino's favorite one. She saw a lot of potential in you due to your small age and she can make you and raise you how she wants so that you become exacly how she wants.

One time, you and her were in Snezhaya for a Fatui Harbingers meeting since she's number 4 of the 11 Fatui Harbingers. You were sleeping verry peacefully in her arms as your entire body was covered by her coat and no one could see you sleeping.
