Block B performed "Very Good" and "HER" at the festival. However, what caught the eyes of the audience was P.O's jacket that had Japanese on it. As August 15th celebrates Korea's independence from Japan, the outfit choice caused more than a few frowns.

Seven Seasons released an official statement, writing:

Hello, this is Seven Seasons.

This is about P.O's outfit at the '70 Years of Independence Sinbaram Festival' on the 15th. We bow our heads in apology to the citizens on P.O coming on stage with the problematic outfit even�though�the stage was to celebrate 70 years of independence.�

His stage was not checked fully before he went on stage. This is a mistake we have no excuse for and something that cannot happen again, so we are deeply sorry.

We send our respect to the patriotic martyrs of the country as well as the fallen who died protecting our homeland that shed blood and sweat for Korea's independence, and we once again apologize to everyone who were offended by this.

Thank you.
