In addition to the rehearsal photos revealed earlier today, B2ST's Doojoon has returned with additional behind-the-scenes photos of his Cube family from their first Korean concert, 'United Cube'. Check them out below! -- "Hello, I'm B2ST's leader, Yoon Doojoon. B2ST, 4minute, G.NA and the other Cube Entertainment family members are all busily rehearsing for the 'United Cube in Japan' concert, which opens on August 25th. The photos I've brought with me here today are memories taken from our first concert 10 days ago. It was a fun 'United Cube' event, though we had to prepare in the rain. As you can see from the photos I took, it was a concert that was so fun to prepare for. We had no idea how tiring everything was. Everyone's faces are so full of brightness. While wishing for the success of our Japanese concert, here are the memories of our last concert. Let's take a trip back to the passionate time of our rehearsal." -- # They look good together, right? "G.NA and B2ST's Hyunseung are posing side by side before our rehearsal. Although they looked tired from all the rehearsals, they both smiled brightly the moment I held up the camera. Don't they look like light is emitting from their beautiful and handsome faces?" -- # Sohyun in Boots? "4minute's Sohyun is making a cute facial expression while in the waiting room. Doesn't she remind you of the Puss in Boots from 'Shrek'? So cute." -- # Immortal Jiyoon! "4minute's Jiyoon is looking at the camera while dressed in her stage outfit.  She's the one who suffered the most because she also had to record for KBS's 'Immortal Song 2'. Although she's tired, she never lost her bright facial expression." -- # Yoseob and Junhyung preparing "This is a picture of Yoseob and Junhyung busily preparing. They grow musically every day, and the results of their efforts definitely shined at the concert. They look just as handsome off stage, right?"
