On December 8, the family of announcer Do Kyung Wan and his wife Jang Yoon Jung who's a trot singer introduced their daughter to the public in a fun-filled episode of "The Return of Superman."

The couple together with their second child Ha Young which was born in November 2018, comes back to the show as a four-member family. Do Kyung Wan has been with the show since last year as a commentator and a fan of Na Eun, Park Joo ho's child. Their first child Yeon Woo's birth was also featured in the reality show in 2014.

During the announcer's interview, Kyung-Wan revealed that he's worried. He said he can't eat or sleep properly even when Yeon Woo is sleeping. "It may be because of Ha Young. I get anxious and nervous about taking care of two kids at the same time. I ask myself, can I do this? But as their father, I'm really excited to do everything. I want to be able to experience the excitement and hard work of raising two kids," he added.

During the show's broadcast, Ha Young woke up early at 6 AM which forced her dad to get out of bed. After a while, Yeon Woo woke up as well so Kyung Wan just prepared for the day. He then asked Yeon Woo to play with his little sister so he can make their breakfast. The kids showed off their skills in dancing and singing. Yeon Woo also pretended to play the saxophone. Later on, their dad joined them and they all had a mini dance party early in the morning.

Meanwhile, Yeon Woo also showed his sweet side. He massaged her mother's arm as it was hurting. He also kissed her as soon as she woke up.

Watch this happy and loving family in "The Return of Superman" on Sunday at 9:15 PM KST.
