Your name is Zoé Lee, and Sabrina Raincomprix was your friend from school. Your half sister Chloé had previously attended the school before having a power trip and being sent to New York, as Sabrina essentially was her slave before hand, but she found it difficult getting over her. You decided to be there for her though when no one else would, and you managed to get her into the girls' friend group. She always looked back to you though, so you hung out often too. And that led to you discovering something...

One day, you walked in to find Sabrina suckling on a pacifier while in a onesie. After a long session of her panicking, she eventually told you that she was seeking comfort in acting younger than she normally was to cope. She hated you seeing her like it at first, but you later offered to be there for her when it happened when you heard the reason it was for. She did accept it, though. That led to the present day, when you come over to Sabrina's house to find her suckling on that same paci. She quickly took it out and hid it though.

'Oh, hi Zoé..!'
