Not "projecting", I'm
speaking from experience. You're the one projecting.
Also, I'm talking about girls from this game and the most realistic of them from my point of view, so of course I'd be referring to real girls I've known as examples. I'm not saying every girl is like this or that it's "normal", I'm not arrogant enough to claim what is normal like it's some kind of undisputed fact.
I also wouldn't really call 5 girls, a lot, tbh. Those just came to mind since I know they're still around, and at least one is trying to turn her life around for her kid.
If you've had experience with girls like Yumi who were born from rape, raised around drugs and violence, ran away from home, robbed people and stores, and still managed to not sell herself or give in to drugs at any point in her life, then holy shit, good for them. Otherwise, you're definitely just being optimistic here.
I mean, you do realize that Yumi and Chika (And Tsuneyo), live(d) in a "ghetto" right? It's called The Old District and it's literally made the likes of Touka cry after just finding out it exists:
Not everyone is privileged or born lucky.
