A perfect ensemble for a music video, of course! As we've reported earlier, artist Wheesung has been gaining tons of respect from his fellow artists for his undeniable vocal talents and has been dubbed by some as "Korea's Best Vocalist." Many of Wheesung's fans are desperately waiting for his upcoming debut in the U.S. with artist Ne-Yo. Ji Sung is set to take on the role of the main character for Wheesung's new music video, "Jooreureuk (Trickling)". A representative at Wheesung's agency stated, "Ji Sung is currently shooting the music video around Boondang, Kyungkido." Ji Sung concluded his role in the drama SBS Swallow the Sun, and took a very short break before moving straight onto the filming of Wheesung's new music video. Although the filming of the drama continued restlessly for three to four months, he gladly accepted the offer of Wheesung without any hesitation. Another representative added, "The two best friends, Ji Sung and Wheesung, have been big fans of each other. Their friendship ultimately resulted in his participation for Wheesung's new music video. We can't thank him enough for accepting it regardless of his busy schedule. We have nothing to worry about." Meanwhile, Wheesung will initiate his promotion for his new album starting from October 8th.
