"SHUKUDAI" is the seventh single from junior reggae singer AN-KUN. The theme of this single is "homework," which all junior high school students have in their daily lives. AN-KUN doesn't want to do it, but Jr. BONG gives him feedback in the lyrics, using his adult experience, saying, "It's up to you whether you do it or not." The lyrics, which are written directly to express the conflict between not wanting to do it and the reality that you have to do it, are turned into a realistic cry from AN-KUN! Keep an eye out for the change in AN-KUN's voice as he becomes a junior high school student and his voice changes.
