Before Sunghee left, the group hinted at the release of a second album on several occasions - it was even mentioned in the last episode of their Self-Cam series.
Obviously DSP wasn't able to release the album with KARA5, but there must have been some hearsay on the album going around prior to February 29 - rumors on the concept, the style, anything. I'd like to ask some older Kamilias here whether they had in fact heard any information on this planned second release. I'm not expecting anything as polished as, say, SNSD's unreleased song "Boomerang", but whatever it may be will probably come to me as a pleasant surprise.
Let the digging begin...
