In order to help Leeteuk's older sister celebrate her wedding, the members of Super Junior were in attendance to lend a hand!

Kim Heechul's appearance on the December 12th edition of SBS's "My Little Old Boy" had him serving as the MC at Leeteuk's sister Park In Young's wedding, which aired on the network. When Heechul appeared considerably more uncomfortable than usual, everyone was taken aback, and his mother revealed from the studio that Leeteuk had served as the emcee at Heechul's sister's wedding a few years before.

Heechul became worked up while witnessing Leeteuk escort his sister down the aisle and said, "I feel awkward." "I'm starting to cry."

Later, Super Junior's Yesung sang the song "It Has to be You" from his "Cinderella's Sister" OST as a celebratory song. "First and foremost, I'd want to express my gratitude to you all," Yesung said, causing everyone to laugh, before getting started. "Thank you so much for agreeing to marry our elder sister," our mother said. "There's something I promised noona a long time ago," he went on to explain. "I'm going to sing the song right now."

Heechul left the stage after the first part of the event to meet his parents, who were in the crowd. "You have to get married as well," his mother informed him. "It's not just about being the MC." The response from Heechul was, "After viewing this, I think it'll be more difficult to [get married]." "We made a decision that you would [get married] by next year," his mother stressed. When you were 40 years old [according to Korean standards]."

Afterwards, he joined the rest of the Super Junior members at their table for dinner. After watching the pair snap photographs of themselves while kissing, Heechul made the humorous observation, "I don't want to get married because I'd be too ashamed to kiss in front of my parents." "How can I kiss in front of my parents?" you might wonder. "You can do it," his mother assured him calmly from the recording studio.

In an interview, Heechul stated, "I'm most interested in Choi Siwon's wedding." "I believe that a large number of foreigners will attend Siwon hyung's wedding," Kyuhyun continued. "Aren't all those business people going to attend as well?" Heechul said, sarcastically.

After then, Choi Siwon inquired of Heechul as to "when do you want to be married?" Heechul said, "When I was younger, I wanted to complete it swiftly, but as I've grown older, I've grown less and less interested in doing it." Having served as the master of ceremonies at a few weddings in the past, I don't anticipate it being a simple task."

Choi Siwon chipped in with a joke, saying, "Among our members, Ryeowook will most likely be the first to marry." On "My Little Old Boy," the members of Super Junior placed a wager that whomever won the game of rock, paper, scissors would have to get married within three years. Ryeowook was the winner of the bet, which was established two years earlier. The members joked that they weren't really "allowed" to get married before Ryeowook in order to honor their commitment to the fans when looking back on their wager.

"If one of our members gets married, I'm going to cry," Kyuhyun confessed in a recent interview. "That's because we know everything about them, starting with their background," Heechul continued. "I believe I'd weep," Eunhyuk concurred, adding, "I think I'd cry." Leeteuk then confessed, "Yesung's mother told me this," he explained. She has stated that she wishes for the members to be married as a group."

Kim Heechul and Choi Siwon collaborated on the MC duties for the second part of their wedding ceremony, bringing the two back together in this capacity for the first time in 15 years, when they were special MCs on "Inkigayo" together. Despite the fact that they just nervously read from the script, which caused their fellow Super Junior members to chuckle, the duo expressed happiness with their own performance at the conclusion of the event.
