This  means talking in Chinese.

  It was a free period and the four were doing their homework in the school library. Hankyung ruffled his hair as he sighed in frustration, pondering over the question. "Hyung, what's wrong?" Heechul stopped reading the comics and looked at Hankyung, the poor boy's hair was sticking out of all places, making him look like a mad person. "I can't.. can't.." Hankyung couldn't finish his sentence as he didn't know how to continue. "Can't what?" asked Heechul. "Aish! I don't know how to do this!" He said in Chinese. "It's okay gege," said Henry. "What? What's okay?" Heechul did not understand a single word. "He said he doesn't know how to do this," translated Zhou Mi. "Hm," Heechul went back to reading.

"Zhou Mi ah, a little help here?"

"No problem, hyung."

"Thanks, you're way better than Heechul."

"I know hyung, I always were."

"Huh? Was what? What are you guys talking about?"

"Hankyung hyung said that I was bet-"

  Hankyung clamped his hand over Zhou Mi's mouth and shook his head, signalling for the stick to stop talking before he gets Hankyung killed. "Hannie, what are you doing?" Heechul put down the book and crossed his hands on the table. "N-nothing.." Hankyung said in a small voice. "Gege said Mimi is better than you," Hankyung's eyes widened since he forgot that Henry was with them, Heechul's eyes narrowed and he looked at Henry. "What?" he hissed. "Gege said.. Mimi is better than you," Heechul stood up from his seat and Hankyung took that as a signal to run for his life. "HANKYUNG!! STOP RIGHT THERE!" shouted Heechul, ignoring the librarian's protest. 

"You know mochi, you should have shut up back there."

"But then I would miss out the fun!"

"You're not as innocent as I thought you know."

"An idle mind is the devil's workshop."
