It was revealed that Kim Jung-tae's eldest son has Asperger's syndrome. On the afternoon of the 10th, a preview video of "Dad and Me Season 3" was uploaded to the TV Chosun YouTube channel. In the video, Kim Jung-tae's eldest son was singing an animation OST in the living room. Kim Jung-tae watched his son's singing from the kitchen and explained, "His interests are unique. To put it positively, they are unique, but to put it negatively, he has hobbies that make it hard for him to get along with other kids."

The family then appeared preparing a meal together in the kitchen. The eldest son, Jihoo, followed only his mother around, continuously explaining the animation's content. Kim Jung-tae's wife confessed, "He only talks about what he likes and doesn't listen to others," adding, "I think Jihoo shows symptoms of Asperger's syndrome." Jihoo wanted to communicate with his family and circled around them, which was his way of communicating.

Kim Jung-tae's wife said, "Our son Jihoo has no interest in others. He simply doesn't care about what other people think. You could say he has a straightforward style," and added, "Because of that, he doesn't understand people's feelings well. On the other hand, it's a good thing that he's so good at English. It's like a double-edged sword."

In 2014, Kim Jung-tae appeared on KBS2's variety show "The Return of Superman" with Jihoo, who was called "Yakkungi," and received much love. Now, 12 years later, Jihoo, who is 16 years old, has grown noticeably, but due to his awkward Korean, rumors circulated that he might have a developmental disorder. Kim Jung-tae expressed his frustration over the rumors, saying, "He said English is more comfortable for him. He has been interested in other languages since he was young. I'm worried too. Because he uses English, his Korean is awkward, so people say he might have a developmental disorder."

"Dad and Me Season 3" will air on the 11th.
