During a recent filming for JTBC's 'Around the World Travel Package', he talked about his family. He had skipped the Switzerland episodes to take care of his mother while she was hospitalized.
He revealed that the hospital had told him that there was nothing for them to do and to prepare himself. While staying by her bedside, he went through the photos on his phone and felt guilty when he found that he had thousands of photos of his children but only two photos of his mother.
The episode will air on March 7 at 11 PM KST.
