Moon Hee-joon said, \"We got a piano at home, and my son really enjoys playing it,\" introducing his son's musical interest.


In the video, Moon Hee-woo sat down at the piano and began playing without hesitation. Viewers were particularly struck by how accurately he performed without referring to any sheet music.


His older sister, Moon So-yul, watched his performance and marveled that he played without sheet music and didn't make mistakes. Moon Hee-joon said his son learned on his own by following videos on YouTube.


Viewers reacted with amazement to Moon Hee-woo's musical talent. Comments poured in: \"Even a professional would call him a genius,\" \"He seems to have perfect pitch,\" and \"He inherited musical talent from his singer parents.\"


Moon Hee-joon and his wife, Soyeol, overcame a 13-year age gap and married in February 2017. The couple welcomed their first daughter, Moon Hee-yul, in May 2017, and their second child, Moon Hee-woo, in September 2022, and have built a happy family.
