"Are you sure about this?" Chorong asked Ivy as they crouched behind some bushes in the school's gardens.

"What?" Ivy asked, her eyes set on the girl sitting on a bench a meter or so in front of them, reading.

"What if she was lying?" Chorong asked her.

"All the other girls you asked said it was Hyemin, as well, though," Ivy reminded her friend of her reconnaissance's results.

"What if they were lying, too?" She just stared at Ivy when he turned to look at her.

"Well, that's what we're trying to figure out, isn't it?" Was the reply.

Chorong sighed and sat back, eyeing her friend up and down.

Is it, like, the cool place to be nowadays," He shook his head to make the word seem even sillier.

"Why, professor?" Ivy smirked, teasing him, "You want to hang out with the cool kids now?"

They all laughed.

"Get serious, Ivy," He said, already walking away. Then he added, "Break's over in five minutes, be sure to be back in time!"

Chorong and Ivy just sat there for a moment. That is, until they remembered the actual reason they had been hiding behind the bushes.

"Oh my God," Chorong met Ivy's eyes, as wide as her own.

Simultaneously, they both launched themselves at the bushes. Peeking over them to find that, indeed, Lee Hyemin was nowhere in sight.
