i dont think so
and he doesnt like to discuss his past
from what i have seen he was a single child until 12, and he spent at least two years on the streets
from the streets part i can infer that he might have once lived in north korea which is a very poor country and is a communist party where everyone's wages is manipulated by the government
otherwise it could just be that he had an abusive childhood(wiki) and was left on the streets or ran away from home when he was young
