Honestly this concept seems as if something's lacking at the moment. Perhaps its only the start since I felt the same way when Ji debuted solo, but yeah like many others I am still not used to her hair and definitely not anytime soon lol.
IMO, for CCM this is a make it or break it kind of concept. Like something that will probably shoot hyomin to total stardom or faring similarly or not as well as Jiyeon, simply due to individual popularity. Her hair is just too drastic a change that either the majority dislikes it, or all of a sudden everyone likes it.
Nevertheless, hope the songs lives up to the usual CCM standard, nice and all, after all she has quite some expectations to live up to after maknae debuted. HYO all the way~~
