Although she's asserted that Taeyang was her final 'ideal man', it seems that the media can't get enough of asking IU about her thoughts on dating and men. While guesting on MBC FM4U's "Radio Dreaming with Woong Dal", IU was asked, "If someone wanted to date you, what would they have to do?" After careful deliberation she answered, "They need to have pretty collarbones." Inspired, her fellow guest Yoo Sang Moo took off his jumper and showed off his collarbones to entice IU. However, she tactfully diverted the missive. "I like it when guys who used to wear clothes that are skin-tight switch to loosely-knitted clothes for some reason. Either way, I like guys with pretty collarbones." When asked if there was anything more to her on-set relationship with "Dream High" co-star, 2PM's Wooyoung, she said, "We just went to eat along with my manager Cody, but it's become a big deal. We went to eat at the family restaurant, and ate rib eye at another time, but Wooyoung paid both times." Later, the star sang her hit song "The Story Only I Didn't Know" live on the air, which drew many praises from the listeners. Source: Newsen via Nate
