B.A.P appeared on the February 7 installment of KBS 2TV's 'Yoo Hee Yeol's Sketchbook' to perform and answer questions in an interview. 

At one point, Yoo Hee Yeol talked about the boys' nicknames, asking who was called 'Busan's Won Bin' and why.  The member turned out to be Daehyun, who explained, "The company was like, 'He's not this and he's not that--let's just throw something out there.'  They were like, 'Antis are fans too--they're all fans.'"

The other members said they had no idea.  Daehyun did not know either until he read a report that stated he was 'Busan's Won Bin.'  They found out that it was the company that had given him the nickname.

Daehyun said, "Overnight, I became a public enemy," making everyone laugh.

The boys also performed Shinhwa's "Wild Eyes."  Check it out below!
