Duo group Toheart appeared on the March 18 edition of SBS's radio program 'Cultwo Show' and revealed which girl group member in their agency was prettiest and their thoughts on an ideal type.

When asked, "Who's the prettiest girl group member in your agency?" Key said, "Girls' Generation?  Sorry, but I've seen Girls' Generation for so long..." then ultimately chose Tiffany.

Woohyun said, "In my agency, she hasn't debuted yet," which would be sure to arise a lot of curiosity.

The two were also asked about their ideal types and it turned out this was where the two close friends differed in perspective, although the MV for "Delicious" showed them fighting over the same girl.  Toheart said, "We're different when it comes to the style of women we like."

Woohyun said, "If I say who's pretty among girl groups, Key goes, 'Really?' in an astonished way.  Our ideal types are so different."  Key said, "Our tastes are similar for other things, but we view women differently."
