Pretending not to know what Kyuhyun was talking about, Kim Gu Ra continued, "I thought this, too, whenever I heard rumors: 'Why Eunhyuk of all people?'  But I can see your charm now."

Siwon said, "He's the Yoo Hae Jin of the idol world," making everybody laugh.

Again referring to past rumors, Kim Gu Ra continued, "I heard there are quite a lot of female idols who learn about love through Eunhyuk," to which Eunhyuk responded calmly, "I like those rumors.  Because that means I have that much charm."
