Yesterday, controversy blew up regarding B2ST's Hyunseung after one fan ranted about the recent bouts of rude behavior coming from the idol on-line, garnering so much attention that even the news media began to cover the topic.

As it became such a huge deal, the idol himself decided to step up and address the hate about his rude behavior, examples of which were ignoring lyrics, dancing without passion, singing in the wrong tone, missing a fan meeting with no explanation, and sleeping during an interview.

On February 23, he posted onto the fan cafe, "Hello, this is Hyunseung.  I apologize for causing concern for a lot of the fans through bad news recently.  If the part that became a controversy was my inexcusable carelessness, I am sincerely feeling regret and am self-reflecting.  I gathered courage like this to relay my sincerity for the fans who love B2ST. Once again, I am extremely sorry for causing concern."

On top of that, his agency, Cube, also stepped up to say, "Hello, this is Cube Entertainment.  We relay the official statement of the agency regarding the controversy surrounding our artist, B2ST's Hyunseung.  Hyunseung is acknowledging everything the overall problem that has been posted on-line recently as well as the whole controversy including his behavior.  Currently, he is taking time to self-reflect.  We also feel strongly that the problem includes the carelessness of the agency, of course, and from hereon, we plan to do our best so that something like this won't happen again.  Once again, we bow our heads in apology for making a lot of people concerned.  Thank you."
