Originally, both Byun Hyun Min and Seo Sung Hyuk were scheduled to take the CSAT tomorrow on November 16, then head to Japan on November 17, to fulfill various promotions until November 28. However, because of the Pohang earthquake, the CSATs were postponed a week. 

Because of this, the two will have to go to Japan on November 17, come back to Korea on November 22 after their performance that day, take the CSAT on November 23, and then go back to Japan as soon as the test is over.

Their label said, "Their promotions are important, but they couldn't give up on the CSAT either. Byun Hyun Min is also a national taekwondo athlete and he has a lot of international competitions next year, so he has to be accepted this year. We had to fix their performance visa and convince the Japanese promotors that it was unavoidable, so two members won't be performing on November 23. They'll come back to Korea after the concert, take the CSAT, and then go back to Japan."

Good luck to both members!
