CN Blue’s fanclub tweeted a new photo of the members along with the tweet, "We finished the Bang Bang autograph session! You can tell that the time for their comeback is near from their changed hairstyles! Please look forward to their 4th mini album ‘RE:BLUE‘ that will be released on January 14th." All the boys had subtle changes made, the one who shocked us the most was Yonghwa's crossing over to the blonde side. Now that Yonghwa is blonde, do you think he'll have more fun?
