It's the 'Radio Star' episode that we've all been waiting for: Zico appeared on the August 31 broadcast of the show and, as promised, the idol brought up his relationship with Seolhyun which had blown up in the media. 

Zico explained, "We were just acquaintances but we started carefully contacting each other. I just grew interested in her without any specific reason, and that's how we slowly developed our relationship and started seeing each other."

Simon D, who was one of the other guests on the show, asked, "Aren't you showing interest when you send a text message? Did you play hard to get?" 

A flustered Zico replied with, "What?" but went on to explain, "I'm not the type to play hard to get. I can't read text messages when I'm working. So I read them when I'm done with work. I think I have to be very careful no matter what I do."
