The JTBC drama "18 Again" cast, Kim Ha Neul, Yoon Sang Hyun, and Lee Do Hyun appeared on the latest "Ask Us Anything"!

The episode kicked off with Lee Sang Min revealing that he had been a judge of Kim Ha Neul's first audition. The actress had participated in an audition to be a model for a clothing brand, and during that time, Lee Sang Min had taken part as a judge to find potential singers. Kim Ha Neul revealed that he was a massive fan of Deux's Kim Sung Jae. One day, her friend showed her a picture of him, and below it, there was a detail about a modeling audition.

Kim Ha Neul continued that it was her big dream to meet Deux's, Kim Sung Jae. As one of the audition judges, Lee Sang Min said that he desperately wanted to turn Kim Ha Neul into a singer, but she refused to sing and dance.

Meanwhile, Yoo Sang Hyun talked about a turning point in his career. During her stint in the drama "Winter Bird," Park Won Sook played as his mother, and there was a particular scene that the actress has to hit him. He went to say that the actress genuinely hit him, and it hurt a lot. He expressed that he has been faking scenes like that in his previous roles, but he was shocked when Park Won Sook immersed deeply into her character and showed him real anger.

The actor then revealed that after being hit in the drama, he went to their home to start practicing the act, and since then, he leveled up his facial expressions and voice. "It was life-changing. From that day, I began to level up my game in acting."

Moreover, Super Junior's Kim Heechul asked how bad Yoo Sang Hyun's acting before "Winter Bird." Then the actor replied that he was criticized a lot since his first drama. He even told the director of the drama "Marrying a Millionaire," which he became part of before finding someone else because he cannot meet up the role's required acting.

The screenwriter and the director told him that they would take full responsibility if he observed that the rest of the production team didn't like him. From that moment, he shared that he read the script throughout the 11 hours on the flight to France for filming.
