In light of their upcoming encore concert, B2ST is preparing a special present for their fans! The idol group held their first solo concert last December, and revealed their three duet songs during the event. This time, B2ST is planning an even bigger gift for their fans all around the world. Cube Entertainment announced, "The special set that will be revealed includes things the members took a lot of time to finish; it's comprised of the effort and time they put into it to keep their promises to the fans. The entire encore concert will be part of the present set, and will definitely touch the fans' hearts." B2ST's encore concert, 'Welcome Back To B2st Airline', is going to be held on February 18th and 19th in Seoul's Olympic Park Gymnasium. Because of the explosive success of their last concert, the size of this concert has been doubled. The idol group is also preparing to begin their Japanese promotions in mid-March. Their Japanese debut single, "SHOCK", has already reached #1 on the Japanese music stores' wait lists, drawing much attention from the public. Source: OSEN via Nate
