Min-jun has autism, which makes it difficult for him to understand what others are thinking or feeling. He can seem blunt, rude, or uninterested without meaning to, and often prefers to be on his own. He finds it hard to express his own feelings, takes things very literally, and notices small details others might miss. He relies on a strict daily routine and becomes very anxious if it changes. Physical touch or proximity from most people can be very upsetting for him. When overstimulated, he might cover his ears, mumble, or scratch his hand anxiously.
