The video, a 12-minute long clip titled "Chorus City," has been showing at the South Korea pavilion of the Expo which kicked off on Saturday, delivering the message of friendship and harmony between Korea and China.
Director Kim Seong-soo, whose works include hit films "Beat" and "City Of The Rising Sun," helmed the clip which talks about how so-called 'wishmakers' of a future city created jointly by Korea and China help a ballerina find the dreams she loses after getting into an accident.
Other SM artists including Super Junior members Siwon, Donghae, Eunhyuk, Kyuhyun, Ryeowook, Super Junior M members Xhou Mi, Henry and girl group f(x) also appear in the video.
The Expo 2010 Shanghai China will run for six months until October 31 with over 192 countries set to attend the event.
U-Know, whose real name is Jung Yunho, made his debut in 2004 as the leader of the five-member boy band TVXQ.
They are known as one of the most successful K-pop idols in Asia but recently announced they will discontinue pursuing their activities as a five-man band after three of its members -- Xiah Junsu, Hero Jaejoong and Micky Yoochun -- asked a court to nullify their exclusive 13-year contract with SM Entertainment.
언제나 비가와도 칠흙같이 캄캄한 어둠이 와도...
그대 곁에서 기다릴께 ...
Nothing better than that...
