Wonder Girls memeber Yenny and 2AM's Jo Kwon have congratulated Sun on her marriage announcement.

Yenny was the first to express herself on Twitter, writing, "Our Sun is finally officially taken!! Congratulations~~^^ Now we can just outright start preparing for her wedding!!! keke".

Jo Kwon was a little more emotional because the pair have been close friends for 12 years. He wrote, "My best friend for 12 years, my lovely friend Sun is getting married!! It feels so different.. I still can't believe it, but I think I'm going to cry my eyes out at the wedding.. Should I sing "Can't Let You Go Even If I Die" at her wedding? hehe. Everyone, please congratulate Sun so she can be happy, and support her ^^". A little later, he again wrote, "I spent half of my life with my friend and we comforted each other when we were feeling down, trusted each other and prayed for each other. We were young but we managed to win over the long, hard road and achieve our dreams, and I'm so thankful that we're happy where we are, Sun. Since we're still young, I'm going to become a friend you can help share your burden whether you're happy or sad", and uploaded a few photos showing their growth.

Once again, congratulations to Sun!
