Huh?
The young woman with the streaked hair suddenly twitched her ears, displaying a puzzled look on her face.
"Hey, you two stop messing around. Did you just hear something? It sounded a bit like an engine noise."
The streaked-haired girl turned back and frowned at the two people behind her.
"Engine? Haha... How is that possible? We are the only car here. Could that old clunker possibly catch up?"
Upon hearing the words of the punk girl, the two of them burst into laughter, showing a face full of disdain.
"No, that's not right! Listen carefully. There really seems to be something!"
The punk girl's expression turned serious, and she spoke to the two in a solemn voice.
Seeing the change in her face, the two were stunned for a moment, and then, although skeptical, they stopped laughing and perked up their ears to listen.
"I don't hear anything..."
One of the streaked-haired youths pursed his lips, thinking the other was making a big deal out of nothing.
