For Hasna (My MC) she would is mentally scarred because in the place that she used live before (Canada) everyone would bully her about her forehead and when she moved to Sunset Bird and became best friends with Jessica (My MC in sunset Bird) Jessica once asked her about her dad and she told her what happended but then everyone started asking and Jessica would kind of protect her by changing the subject cause she knew she was scared to talk about it, and once someone mentioned her forehead size and made fun of it (they were in a roast battle) she didn't cry infront of them but when she got home she cried her eyes out.. Her mom Opal knew about it and tried to encourage her and give her confidence and it kinda worked.
But she hides her forehead with her bangs and when she was 10 (Step 1) she would sometimes almost all the time not hide it, but she doesn't do it anymore only with Qui she doesn't hide it and sometimes rarely with Tamarack.
