Along with its modern fairytale type of story, "The Heirs" also boasts a cast that not only possesses excellence in acting, but outstanding visuals.

"We play around before the filming, but once the camera starts rolling, we become extremely serious," revealed actor Kim Woo Bin who plays Choi Young Do in the drama. He added, "Everyone has been fully absorbed in the drama, including myself."

Choi Jin Wook also talks about his character Kim Won. He said, "Kim Won has a lot of complicated emotions, so as his actor, I think about him a lot. I work hard to portray his feelings of love and hate for his brother Kim Tan, as well as his love for Hyun Joo"

According to a representative, "These young actors of the same age are giving all their energy and responsibility for the production of this drama. Please anticipate the charismatic and sexy teenage love story of the six men who bring life to "The Heirs" starting the next episode.

Meanwhile, the cast also revealed several behind-the-scenes photos in which they enjoy their time off with their fellow actors. They are noticeably seen laughing and goofing around, giving off a sense of playfulness to the otherwise serious drama.

Lee Min Ho revealed, "In my previous dramas, I have always been the youngest, but I'm the oldest cast member for this one so I feel responsible for them. The cast gets along and we all have fun filming."
