Character growth In miyo

This is something that irritates me bad😭 but why do so many people act like miyo wasn’t abused her whole life and that’s why she acts that way. Just because she’s in a safe place doesn’t mean she’s automatically going to have this super big character change when it takes time,love and patience to heal from abuse.. and it’s like are people not paying attention? Please tell me I’m not crazy 😭💀
