ZE:A's Jung Heechul will feature in Gavy NJ's Sunflower performance on this week's Mnet's M! Countdown! This will be the first time Heechul is featuring in a performance ever since he debuted with ZE:A. Like the previous featurings from H-Eugene, BEAST's Doojoon, MBLAQ's Mir and F.cuz's Jinon, he will showcase his rapping skills. Hee Chul commented, "I've always liked Gavy NJ sunbaenim's song, so it is an honour to be able to feature in their performance. I am very nervous because it's my first featuring in a performance. I am practicing hard to make sure I do not make any mistakes." Stay tuned to their performance tomorrow, February 18th!
