A rep of Trouble Maker's agency Cube Entertainment revealed, "After a lot of thought, we decided to release an album version with a 19+ rating. �You will probably be able to see even more sexiness than the current Trouble Maker has shown."

This 19+ album version will be packed with highly shocking images that have not been revealed on the internet. �However, the definite time of release has not yet been decided. �The agency plans on releasing this new version approximately two weeks after the original album is released so you may have to wait quite a bit longer before you get to see any of these "shocking images."

Trouble Maker's new album is already receiving a lot of attention even a week before its official release as noticeable by its popularity on the pre-order music charts. �Trouble Maker will be revealing their new music on various music sites on the 28th and their actual album will start selling on the 31st.
