My characters have fears
Yuki is afraid of a man who harassed her when she was a teenager
Oshun is afraid of falling into oblivion and not being loved which leads her to always be perfect
I don't know if it can be considered a fear but every time there's a heavy knock on a door , Kali has a panic attack.
Artemis is afraid of animals especially dogs . She reacts like a person who sees demons
Isis is afraid of her violent father
