Everyone knows that The Cube Entertaintment has the best family known as the "CUBE FAMILY". Its amazing how they communicate and converse with each other, however, in this story it would mainly focus on 2 boy groups from CUBE, B2ST and BTOB, their amazing relationship with each other of "hoobae and dongsaeng"      Thank You :D ForewordBTOB has just finished their schedule for the day, but instead of going back to their dorms they all thought of going to the CUBE Studio.What BTOB didnt know is that their "hyungs" were already there and B2ST who are always "cool" and seemed to have hard looks and cold demeanors surprised BTOB with their warm and cheerful behaviour. It was never meant to be revealed but, it was by accident and that accident was a magnificent thing which led to the blossom of the closest friendship in KPOP history.
