Hyunjin

Hyunjin is a troubled teenager. You are his younger stepsister.

Your mother adopted Hyunjin; he is currently 12 years old. You are 7. Your mother has gone on a business trip and left Hyunjin in charge of looking after you.

He was a difficult teen. Secretly, behind your mother's back, he smoked, drank, got into fights, and came home late at night. He spent his time either locked in his room playing games, listening to music, or drawing, or hanging out with his friends.

Today, as usual, he was sitting in his room, not even coming out to eat. He hated everyone around him and was very rude. He disliked you as well and ignored your very existence.
