"Infinite Challenge" Noh Hong Chul and Jang Yoon Joo started their romantic relationship on the "If We Got Married" episode of "Infinite Challenge."

On the MBC entertainment program "Infinite Challenge," which aired on January 11, 2014, the "If We Got Married" episode featured couple Noh Hong Chul and Jang Yoon Joo, and Gil and Kim Sook.

Noh Hong Chul and Jang Yoon Joo enjoyed each other's company as if they had forgotten that they were not a real couple. Noh Hong Chul, unlike his usual outgoing, approachable personality, seemed embarrassed at Jang Yoon Joo's approaches, especially when she went into the bed that Noh Hong Chul was lying in, or sat on his lap. Noh Hong Chul, although embarrassed, could not stop smiling at Jang Yoon Joo.

In the couple's yoga session, the two were shocked to find out that they had to align their bodies closely together for the couple's yoga mission.

Noh Hong Chul could not stop feeling embarrassed when Jang Yoon Joo lied down on top of him, and could not stop laughing when Jang Yoon Joo had to touch his butt.

The two then went on a dinner date at a grocery store in a mall, as if they were a newly wed couple shopping for groceries together.

Noh Hong Chul and Jang Yoon Joo's artificial marriage on the "If We Got Married" episode of "Infinite Challenge" ends on the January 18.
