She's just a 1st year in junior highschool. She's just 12-13 yo at best. I know she's acting like a brat, but most teens at her age act like a brat. Yes, she's gloomy, insecure, and tbh, a bit annoying, I'm not defending her for her action. I'm waiting for the explanation of her story.
I think it's going to be a long ride of miscommunication. I hope not, sure.
But seeing how long the photoshoot in the last arc, girl only can hope.
