As to why he decided to go public, Lee Kwang Soo said, "Not because there's a special reason but because it didn't feel right to lie. It remains even after time so I didn't want to lie, and she also felt the same way."

The reporter mentioned marriage. To the tricky question, Lee Kwang Soo said, "Save me," then explained, "Marriage doesn't seem real to me yet. There are many people around me who've already got married but I don't think I'm adult enough yet."
