I'm glad they are going into ballads now! They all have suitable voices for ballads and especially after I heard seungyeon's Warrior baekdongsoo OST I was all hype up for a KARA ballad! There's a lot of market for a ballad in Japan, and I believe that it'll be a really smooth fusion seeing as KARA's songs has always been kpop (or jpop) focused but never too auto tuned or digital.
