Born in 2004, Lee Eugene first rose into stardom for his acting in the hit drama "SKY Castle."

In 2009, Eugene then joined MNET's reality and survival show, "Produce X 101," as an independent idol trainee. Despite being a rising child actor at that time, Eugene explained that he dreamt of becoming an idol actor after being inspired by EXO D.O.

He said, "I saw EXO D.O. (Do Kyung Soo) in his film 'Swing Kids' and I want to become like him," emphasizing how he shines as both an actor and idol.
