Group BtoB and Cube Entertainment (Cube)'s Exclusive Contract ReContract have been virtually misfired. According to a number of officials on the 6th, BtoB has taken the strand toward the end of the Exclusive Contract with Cube last week and not the ReContract. However, it is known that the reason for the misfiring of the re-Contract is not a Payment problem that was previously known. On the first day, BtoB was contacted by other companies ahead of the second re-Contract with Cube, suggesting that the group offered 6 billion won in Payment. However, according to industry sources, it is true that BtoB is a rare team with the ability to produce song performance, and since it is performing arts and acting, there are many places that have "suggested" a large amount of Payment to BtoB. However, Cube and the final Payment were also coordinated. However, negotiations broke down in the process, demanding that Cube share a portion of the team's total sales on condition that it uses the BtoB trademark. BtoB debuted in March 2012 with 'Secret', and was loved by releasing hit songs such as 'Ruptured Bambun', 'It's okay', 'Prayer', 'I miss you', 'I can not do without you', 'Beautiful and sick'. Especially, all members were recognized as a complete talented person with solid vocal ability and performance ability.
