For Ellie's voice this is the type we are going for: 

Ellie character description: She's the type of kid who wouldn't sit still at school. But despite that, she's not overly loud or obnoxious. She hates adults and authorities in general, and thinks they are all idiots. She has a bit of a laid back/one-of-a-kind bamf attitude and is quick to anger. But on the inside she's just a very broken and insecure little girl.

First: Narration read

Second: Been punched in the stomach, so out of breath and angry

Third: On the verge of tears, depressed. 

If you are able to speak Korean, that will be a plus because there will be mentions of different Korean names that are a bit difficult to pronounce.
