That would also explain the fact that Jun didn't know how to use a phone or even what it was. He didn't know how to interact with others along with his sudden capability to get an unimaginable amount of gold out of nowhere. The fact of the matter was that nothing Jun had said made any sense. He had lied about being nothing but a baby sitter for Julius which was how he tried to explain his reasoning for having so much money. He had told the girls that were accompanying them on their short stay that Julius' parents were wealthy and had given the gold to Jun so that he could get something nice for Julius.
