On the episode of KBS 2TV "Happy Sunday - Superman Returns," which aired on December 1, 2013, Tablo met with another member of Epik High, DJ Tukutz. Kim Ha Ru, daughter of Tablo and Kang Hye Jung, transformed herself from her usual chic attitude into a talkative, lovely older sister in front of Yoon Wu, son of DJ Tukutz, who was only 11 months old.

Ha Ru placed Yoon Woo on a toy car and gave him a ride, and clapped her hands to attract Yoon Woo's attention, showing her trusty sides as an older sibling. Ha Ru referred to DJ Tukutz' son Yoon Woo as a "baby," but she herself was undoubtedly a baby as well, who was obsessed with the children's TV show, "Bbororo."

Tablo, who witnessed Ha Ru's transformation from her usual chic attitude into a lovely older sibling, said, "To be honest, I never thought of having a second or third child. But I think my wife Hye Jung will realize the importance once this episode airs," making the audience laugh.
