Singer and songwriter Yoon Sang and actor Shim Hye-jin's son will make their debut as a new male group of SM Entertainment (SM). As a result, Yoon Sang's first son, Lee Chan-young, is a member of SM's new boy group debuting in September. Lee Chan-young, who was born in 2003, announced his face and name while appearing in an entertainment program with Yoon Sang in the past. In 2018, SBS entertainment program 'Single Wife 2' depicts the recent situation of the Yoon Sang family living in New Jersey, United States of America. At that time, Chan Young, who dreamed of Sooyoung, gathered attention with his idol-like appearance and dignified appearance. At that time, Chan Young-gun, who was a prospect of the United States of America Junior Sooyoung, confirmed that he had a new dream of K-pop idol and had been Speech for a long time. As a SM trainee, Chan Young-gun, who has been systematically trained in SM, will finally go to the music industry in September with Eun Seok, Seung Han, and other members who were released as NCT, Shotaro, and SM Rookies. Above all, he is the son of his father Yoon Sang, so he is proud of his musical talent. He inherits the delicate musical sense of Yoon Sang and seems to show off his unique singer gene after his debut. This is why the birth of a superstar singer and father is welcome. SM Rookie Boy Group is in the midst of The Speech with the goal of debuting in September. Recently, I shot my debut song music video successfully in United States of America Los Angeles (LA) and returned home. Those who have already received great expectations from global K-pop fans are expected to play a big role in the world as the strongest 5th generation stone 'monster rookie'. Especially, it is expected to continue the lineage of SM group such as H.O.T., Shinhwa, Fly to Sky, TVXQ, Super Junior, Shiny, Exo and NCT.
