On January 19th, Cube Entertainment’s first unit group Trouble Maker, which is comprised of 4minute’s HyunA and BEAST’s Hyunseung, shared some behind-the-scenes photos through Ilkan Sports.

HyunA also wrote a personal letter for fans which read, “Hi all, this is HyunA. We had a short but impactful promotion as Trouble Maker~Thank you for showing so much love and support. We always did our best to show a better side of us and an improved stage, but I’m not sure how you guys felt about it. I still have a lot of regrets T.T. Trouble Maker promotions have come to an end after last week’s performance at the 26th Golden Disk Awards in Osaka, but I’ll be going on stage as 4minute next month, so please wait just a little for me~Hope you show lots of love for 4minute’s new mini album~^^”.
