Sunggyu appeared on MBC's 'Radio Star' on June 3 and talked about a wide variety of topics from Park Shin Hye to his dating experience.

Regarding the pretty actress, he revealed that he was close to her because not only were they the same age but they were also close to Heechul. �I recall a picture the three took together at her mother's restaurant!

He complimented her, saying, "She's extremely easygoing and has a good personality." When asked if she were his ideal type, he stopped talking, making everyone laugh. He chose Han Ye Seul as his ideal type, but she's taken, buddy!

Sunggyu also had a lot to say about MC Kyuhyun. �Kim Gu Ra asked, "What's that about Kyuhyun telling you to leave because he was on the phone?" �Sunggyu asked Kyuhyun, "Can I talk about this?" then continued, "While we were taking a break during filming, I went into the room to sleep a bit, but Kyuhyun was on the phone, so he asked me to leave."

Hearing this, Kyuhyun said, "Did I do that?" then continued, "I must've been on the phone with my mom. �I like my mom," seemingly trying to brush it off as so, but the other people on the show teased him with, "There's something going on," "It must've been a girlfriend," and more.

Kyuhyun said, "That probably was not it," but Sunggyu added, "He was on the phone very often," making everyone laugh. �Were you talking to a girlfriend, Kyuhyun? �How cute if so.

Kyuhyun asked him on today's show, "When was your last relationship?" and he replied, "It has been a really long time." �Kyuhyun followed up, asking if Sunggyu was the type to do special events for his girl.

"I am really bad at those," Sunggyu replied. �"I can't even express myself well. �I do say honestly that I like her."
