The PD of “Elementary School Teacher” (literal title) thanked 2PM’s Nichkhun for his small cameo appearance, which involved the singer answering a single dictation question against f(x)’s Amber.
PD Kwak Seung Yeon was asked during an interview whether the competition was too easy for Nichkhun, to which the PD replied, “Not at all. The other idols had a chance to study material related to the questions beforehand while he didn’t. Though Nichkhun is good at dictation because he’s studied Korean for longer, he doesn’t know proverbs very well. So if the question had been about proverbs, the tide may have turned against him.”
Kwak Seung Yeon added, “We weren’t initially planning to just do a sudden death round. We were actually going to ask one question about idioms, proverbs, and dictation each. Kang Ho Dong brought up the idea to make it a sudden death match to make it more fun.”
Stating that it may have been advantageous for the singer to have more questions asked because he’s been studying Korean for much longer, the PD added, “Sudden death matches are like penalty kicks. There’s a bit of luck involved. Nichkhun agreed to the change as it would make the show more interesting.”
The PD revealed that Nichkhun had even stated he would come back to learn more Korean if he lost. Kwak Seung Yeon added, “Actually, I hesitated a lot about doing it [inviting Nichkhun]. Though I’m friends with him, he has quite a busy schedule. But he was happy to come and wait for 10 hours just to solve that one question. It made me feel better when he told me that the changes made the show more fun and nerve-wracking.”
