Jang Kiha was asked again about his girlfriend IU on the June 28 broadcast of MBC FM4U's 'Tei's Dreaming Radio.'

When asked, "What song out of IU's songs do you like the most?" and he replied, "My favorite song is 'Glasses.'  I like both 'Glasses' and 'Knee,' but I feel like 'Glasses' is a bit less famous, so I'm intent on getting it out there more."

He was then asked, "Among the events you've done for her, which event did IU like the best?  Also, how do you guys date?" and he replied like a good sport, "There are many.  I can't call them events, but I express my feelings.  Right now, IU is filming a drama.  There is one time I went to the set and showed her my support.  These days, there's no time to date, but we are the type to date fairly often.  We're doing well together."
