The December 17 installment of SBS's 'One Night of TV Entertainment' headed over to Sungmin and Kim Sa Eun's wedding, interviewing other celebrities and SM artists like Shindong and Kangta!

At the ceremony, Shindong said, "Honestly, I did not know he would get married so quickly. Nobody knew.  Congratulations, of course," and revealed each member decided to give them money individually and in secret as the wedding gift.

Shin Sung Woo, who was in the musical 'Three Musketeers' with them, said they were suspicious since the musical, saying that they probably did not show signs of affection around the others but in private.  He stated, "When they did kiss scenes on stage, they probably did them with sincerity."

Kangta said, "The bride cried a lot when Ryeowook sang the congratulations song.  I think they will live well and be lovey dovey."

In addition, MC Sooyoung said, "There was a congratulatory atmosphere because of their new start.  The older seniors were probably envious.  I think Kangta was envious.  An especially cold winter is approaching."
