According with this quiz ( http://www.koreaboo.com/spotlight/what-does-your-favorite-k-pop-boy-group-say-about-your-personality/), those who like Cnblue are Intellingent:
" You're clever, more-so than most people realize. You do not always let on how truly genius you are, but you definitely have the right perspective on things, and you just know that you see things more clearly than most. So what are you gonna do with your super brain powers, smarty pants?"
Nice description, I like the association CNBLUE = Intelligence !
