BNK48 is an idol girl group, whose 26 members are girls from 13 to 23 years old. The concept of the band based on an ordinary, but dedicating character.In each single, only 16 from 26 members are selected to be part of it.So, every girl needs to put all of her effort in practicing and improving herself, also inevitably competing with each other.... while trying to maintain their friendship.They soon realise that dedication is not the only key factor and hard work doesn’t always lead to success.
