We previously reported that CNBLUE would be making their major Japanese debut with their single, "In My Head". Their MV teaser has finally been released, and we're liking what we're seeing! The video has an overall dark and�eerie�vibe to it, but the boys are just oozing charisma as they rock out to their latest single. CNBLUE is opting for a more masculine style this time around, and smashing objects in the background definitely adds onto the rock nature of the song. CNBLUE will release their major debut single on October 19th, so be sure to check back with allkpop for more details! Tip: sachiko erin
