"Hankyung, what is the answer to this question?"

"......"

"Yes? Do you know the answer?"

"Yes, seonsaengnim."

"What is it?"

"......"

  Hankyung scratched the back of his head as he struggled to think on how to tell his answer. "Erm... ah.." Mrs. Park sighed as she put the chalk back into the box, she knew Hankyung was a foreigner. Today, they were learning idioms and the boy clearly had problems with it. "Ah! Kill two stones with one bird!" Hankyung piped up. "Hankyung.. it's kill two birds with one stone," corrected the teacher. The class snickered while pointing at Hankyung, clearly enjoying his mistake. "Yah! Leave him alone!" Heechul stood up and glared at everyone, making them shut their mouths at once, Hankyung looked at Heechul in gratitude and the older just smiled encouragingly at him. 

"Hannie.. you really need to improve your Korean.."

"Waeyo? I did well, didn't I?"

"Pfft. Kill two stones with one bird? I'd like to see you do that! Maybe you should leap before you look too!"

"Shut it Chullie."
