Actor�Yoo Seung Ho and singer IU's special relationship has become an issue yet again. On the April 30th, KBS 2TV's 'Entertainment Relay' met with the voice actors of the animation "The Hen That Left The Garden" -�Choi Min Shik, Moon So Ri, Park Chul Min, and Yoo Seung Ho - for a brief interview. While the animation has garnered interest because IU sang on the soundtrack, more attention has been gathered because IU and Yoo Seung Ho have sung a duet together in the past. In July 2010, IU and Yoo Seung Ho teamed up for "Believe in Love", which was dedicated to poverty-stricken children. Later that year, IU revealed in an interview that amongst the men that she's sung a duet with - including Sung Shi Kyung, 2AM's Seulong, Yoo Seung Ho, and Na Yoon Kwon - Yoo Seung Ho was most like her ideal type. Yoo Seung Ho shyly spoke of his same-age friend IU saying, "We're friends. It's still a bit awkward." �To this, Park Chul Min�insightfully�suggested, "Love starts because it is awkward."
