Nucksal shared an update on his parenting. On the February 11th broadcast of MBC's "Radio Star," Nucksal appeared alongside Lee Dong-jin, Ahn Hyun-mo, and Gwe-do to share his parenting experiences. He revealed that his first son is 3 years old and his second son is 94 days old. Suffering from sleep deprivation due to childcare, he said, "I don't have much to talk about. I can only talk as a parent."

He also shared an episode about his first son. Nucksal recalled, "When we gave food to our first son, he would fall asleep. So even though it was our first time raising a child, we thought, 'This is manageable.'" He then explained the background of having his second son. Nucksal recounted a bizarre incident where the gender of his second child was mistaken. He said, "The doctor initially said it was a daughter, so I thought, 'Everything is complete. We are a perfect family of four.' But when we had a detailed ultrasound to see the baby in the womb, there was a definite sign between the legs, an unmistakable piece of evidence that no one could deceive."

His second son had heart problems and underwent surgery but is now recovering healthily. Nucksal explained, "But he has a sensitive temperament. He is very different from the first son. That's why I can't sleep. I'm almost like a zombie." He added that although he and his wife take turns caring for the children, he wakes up to sounds even when sleeping separately due to his sensitivity. Nucksal said, "Sometimes I thank my wife when I go to the bathroom for no reason."

Kim Gu-ra pointed out with a laugh, "It seems like you have a lot to say. Why do you say you don't?" Nucksal married a non-celebrity six years younger than him in September 2022 and has two sons. His honest stories about parenting resonated with many people.
