B2ST Hyunseung will not be attending the Cube Entertainment concert 'I Want Cube Pop' in Macau. 

On March 4, 'Cotai Ticketing' announced, "We have received the news that B2ST Hyunseung will not be attending 'I Want Cube Pop' concert due to personal reasons."

Cube Entertainment is scheduled to have a concert in Macau with 4minute, BTOB, and B2ST joining the event. However, B2ST will have to attend with just five members as Hyunseung will be absent.

Netizens are assuming that this might be related to Hyunseung's recent controversy over his careless behaviors. Many fans have turned their backs even after the official apology. 

Whatever the reason might be, 'I Want Cube Pop' concert will be held without Hyunseung on March 5.
