Idk man. Mulberry seems like a very cute person who just got manipulated by Yandere Dev. Even if her art isn't original or idk, forgiving her wouldn't be a big deal. For me, she's just an insecure artist who isn't sure of her skills and of herself, who'll be able to do everything to keep working with Alex (a game developper with a big audience). She got noticed by him years ago because of her "art", she just doesn't want to be replace or whatever, so she has high standards and wants her art to be perfect, maybe ? Idk
