U-KISS' Dongho got a 'back hug' from genius guitarist Jang Ha Eun on the latest 'Star King'.

On the March 16th broadcast, siblings Jang Ha Eun and Jang Ha Jin prepared an amazing guitar performance. Dongho was unable to look away from their expert guitar playing, which Rainbow's Jaekyung pointed out.

He explained, "She's so pretty playing guitar." MC Kang Ho Dong then suggested Dongho and Jung Ha Eun play the instrument together. The professional guitarist tried to lead Dongho, helping him from behind. The idol was unable to hide his nervousness, getting giddy with laughter from the 'back hug'.
