On October 18 episode of MBC's television show 'Those Who Cross the Line', Song Il Kook made a guest appearance.

He continued, "When I told him that I was going to meet historian Seol Min-seok today, he got really excited. He even wanted me to get an autograph of him on his book."

Song il Kook sighed and responded, "They really don't listen to me well nowadays."
He went on, "Minguk is very smart just like my wife, but the problem is, he is always telling me off with everything I do."
He laughingly added, "Recently, Manse told me that he wants to run a donut store in the future."

The triplets returned to Korea after living in France for about a year last year.
