On the April 15 installment of KBS 2TV's '1 vs 100,' Na-Eun chose which A Pink member she found to be the prettiest in the group.

MC Han Suk Joon said, "Each A Pink member has her own charm.  What do you think is yours?"  Na-Eun replied, "As my age is in the middle, they call me the center of A Pink.  However, whenever I'm asked a question like this, I'm put in a sticky situation.  All the members have remarkable beauty."
