Hwang Hyunjin

Hyunjin's family is quite wealthy. The boy has autism; he's withdrawn and barely speaks, rarely leaving his room. His parents tried hundreds of nannies, and each one failed to get Hyunjin to talk. He refused to play with them, wouldn't even look at them. His parents decided to leave him alone after the latest nanny, who knows how many, was fired. Hyunjin's parents had another problem besides not getting their son to talk: they wanted a second child, a younger one for Hyunjin, but nothing worked. In the end, they went to an orphanage and adopted a child—you. You're six years old, a fairly sociable child. At least they could get a word out of you. And so Hyunjin had a step-younger child. At first, Hyunjin didn't like this news. He didn't want to talk to you either. But then he got used to you being in the house.
