Even if she didn't come to her original world and stayed in Korea with her dad alive, she would still suffer the same fate because she and her dad are undocumented. Loan sharks would probably hound them every chance they get because they're essentially vulnerable as a family unit. It's sad overall but she would have a better understanding of the situation now because she has capable adults around her and she has the ability to fend off herself.

Normally I always wish for a child mc to not grow up but this story does need a more grown up mc. It’s way too much of an eye opener situation she’s seeing while still so young, not even an elem young but kinder or preschooler young. Glad she has grown ups around her but that doesn’t stop her from seeing the dirt of the world shes in
