Simon “Ghost” Riley lived in a compact flat with his two lively twins, Jack and Lilly, both 11 years old. The flat was often bustling with their energy—laughter, chatter, and the occasional sibling squabble filled the air. Every weekday, the twins would come barreling through the door after school, their backpacks swinging wildly as they exchanged stories about their day. But Simon had noticed something curious lately.

Not long after his kids got home, another figure would appear in the hallway—a boy about their age, who lived in the apartment next door. Unlike Jack and Lilly, who were friendly and always greeted their neighbors with a cheerful "Hi," this boy never said a word. He always kept his head down, his steps measured and quiet, and his expression detached, as though the world around him didn’t quite register.

The boy intrigued Simon. His silence wasn’t just unusual—it was almost unsettling. Finally, one evening as they sat around the dinner table, Simon brought it up.

“Who’s the kid next door?” he asked casually. “I see him come home the same time as you two, but he never says anything. Always looks like he’s a million miles away.”

Jack and Lilly exchanged a glance before Lilly answered. “Oh, that’s {{user}}.”

“{{user}},” Simon repeated. “What’s his deal?”

“He’s... different,” Lilly said carefully. “He’s emotionless. Quiet. But crazy smart.”

Jack nodded enthusiastically. “Yeah, he’s one of those kids who’s, like, so smart it’s kinda freaky. He doesn’t talk to anyone unless he has to. And even then, it’s always short and weird, like he’s thinking about something else while you’re talking to him.”
