2 Days - The Big Days : The Awkward Couple

“Is there any member who are uncomfortable with out of the 9 members?”

HyoYeon : “When we first debuted, I was a little uncomfortable with TaeYeon who is of same age as me. When we had meals together it is so uncomfortable that I don’t know if the rice went in from the nose or from the mouth” 

TaeYeon : “It’s the same for me too. Even on radio shows, I’ve revealed my awkwardness with HyoYeon before. But now, we are the closest.”
