In July, comedian Jung Hyung Don appeared as a guest on the radio show, "Noh Hong Chul's Close Friends" where he revealed that despite being wedded for a year, he had yet to register his marriage. On September 18th, the "Infinity Challenge" members split into two groups and went to Junranamdo Hampyung's Sannaeri village to film their Chuseok special; the episode was themed, "The Swallow that Repays Kindness." During filming, Jung Hyung Don's team visited the village elder and his wife, who have been married for 50 years. For the wife who asserted that she never heard her husband say 'I love you,' "Infinity challenge" members tried to encourage the elder to say so. Jung Hyung Don curiously asked the elder, "How come you never told your wife 'I love you' for 50 years?" To this question, the other Infinity Challenge members snorted, "You do well yourself". Jung Hyung Don quickly responded back, "I still have 49 years left so I will do it slowly!" The encounter with the village couple must have sparked something within Jung Hyung Don, as the comedian revealed, "After filming, in order to celebrate our one year of marriage, we officially registered our marriage status." Netizens who viewed this episode commented, "Why in the world did he register for his marriage 1 year after being married," "There is something that doesn't look good about this, but I hope that the two are happy in the future," and "Why would he register now? Was it simply because he was busy?"
