Yoon Doojoon, the mighty leader of CUBE Entertainments B2ST, was busy replying to fan messages when one fans message caught his attention.. Annyeong Oppa! I followed you on twitter! Why not make a facebook account? (: FACEBOOK. Hes been hearing that website from his fans for weeks now. Whats so big about that website that his foreign fans always suggest it to them? Today, he decides to find out.   As soon as he pressed "Enter" a website appeared. Its homepage was pretty simple, nothing interesting. The color blue surrounded it, just like how light blue was everywhere in Twitter. Its time for the moment of truth. He wants to end the curiosity now... Starting that day, the Facebook craze in United Cube started... ForewordIve seen SMTown, SHINee etc. Why not UCUBE, right?This story features the interactions of UCUBE Artists in Facebook. It also features some famous OTPs ;)
