Zico admitted he's most harsh to his fellow Block B members.
On the July 18 airing of MBC's 'Radio Star', Zico was asked about his directing style as a producer. He first answered, "It depends on the singer," and shared, "I'm most harsh with Block B members. In our early debut days, feelings were hurt because I was straightforward."
Zico added, "But after about 2 years, the members knew that I have no intention to hurt their feelings."
