On the 3rd, KBS 2TV's 'The Return of Superman' uploaded a video titled 'JamJam is Back: Revealing our Second Child, Hee-woo, for the First Time' on the official KBS YouTube channel.

The video featured Moon Hee Jun and Soyul, along with their daughter Hee-yul (JamJam). Hee-yul introduced herself, saying, "I am Moon Hee-yul, and my fetal nickname was JamJam. I am eight years old this year, seven years old in international age."

When asked by the production team how she felt about returning to 'The Return of Superman,' 

Hee-yul smiled and said, "I really, really like it." 

Hee-yul appeared on 'The Return of Superman' in 2019 at the age of three. Her unique cuteness and attentive care for the production team melted the hearts of virtual aunts and uncles online.

Even now, five years later, Hee-yul continues to show her kind heart by sharing snacks with the production team after greeting them in the morning.

Later, Moon Hee Jun appeared holding his second son, Hee-woo. He sparked anticipation by saying, "Our second child was born, but we haven't revealed his face yet."

He continued, "The second child has been special since he was born. I debuted on September 7, 1996, and my son was born on September 7, 2022. It feels like he was born to continue my destiny," expressing his affection.

Meanwhile, Moon Hee Jun and Soyul got married in February 2017 and welcomed their first daughter, Hee-yul, in May of the same year.
