Well, at least not from where I come from. Where I come from, even when one parent is not available the other parent steps up. In at the worst, the extended family members come in to take care of the kids. But to leave little kids to fed for themselves? Never seen that.
I have a very genuine question for the Koreans on this thread (and maybe everyone). Are there really parents who abandon their kids like this in the real world? Like they just pack their things and leave their children alone and go live a comfortable life somewhere else?
