Actress Lim Joo Eun breaks out of character by showing her aegyo for "The Heirs" behind the scenes photos.

She plays the role of Jun Hyun Joo, a studious and serious but slightly awkward high school teacher at Jeguk High School, and she is also the love interest of Kim Won, Kim Tan's older brother, who is portrayed by Choi Jin Hyuk.

In the most recent episode of "The Heirs" Kim Won catches a cold, and Hyun Joo takes care of him by cooking porridge. While the cameras are not rolling, the actress puts on her aegyo and shows a more lighthearted side to the audience by playing with the spoon, garnering attention from viewers who are happy with her change of image from a serious character to a cheerful actress.

According to representatives from the drama, "Lim Joo Eun serves as the staff's mood maker, and she does not only give off cheerful energy, she also gets along well with the other members of the cast. They practice together and monitor each other, showing just how much of a team they are."

Catch Lim Joo Eun on "The Heirs" every Wednesday and Thursday.
