Jung Hyung Don and Tae Yeon met in "Be Happy Today" but they did not mention anything about "WGM" at all.
Of course there are special cases like Jun Jin and Lee Si Young who got together for real after they left "WGM" and Kim Yong Joon - Hwang Jung Eum who are actually a real couple even before the show. They raised the boundary so much that even fans are requesting them to date for real.
Nowadays we cannot see Andy and Solbi together anywhere.
Sin Ae got married after she separated from Alex, Crown J and Seo In Young do not have any correspondence with each other.
I can see them falling for each other more and more.. And kim so eun the cute wife, an easygoing and tough ..You can feel their love towards each other, though this is just a virtual marriage but for them as an artist showing/expressing their feelings are so natural.
