XO EXO CIRCUS consists of 6 members. They go by the names Kai, Lay, Tao, Chen Sehun and Baekhyun. Why the hell would such a circus have a chat room similar to a fan sign but can talk for a limited amount of time. Back on track how are they so popular? Well

1) Young

2) Handsome

 3) Good at what they do

Last, they attract ATTENTION. Lots of it to, particularly female (exception to men too.) all these points just make them more famous and well known. Starting of small and going up made them successful in what they do and they love it.
