2AM leader Jo Kwon confessed that he was against Wonder Girls leader Sunye going public about her relationship.

When the topic of Sunye's relationship came up on the March 7th airing of MBC's 'Radio Star', Jo Kwon sighed and remarked, "I'm getting a headache."

"Sunye is a friend I've known since I was 13," he began. "She is extremely strong-willed, passionate, and ambitious. So much that I was a little intimidated by her, and she felt more like a noona to me."

"But once she started dating..." he continued, suggesting that Sunye had changed after falling in love.

"I thought maybe the announcement would cause her some emotional pain, and I tried to stop her," Jo Kwon admitted. "But a few days ago I ate with her and asked how she was doing. She is really happy and healthy."
