Lim Joo Eun, who plays the role of Kim Won's (Choi Jin Hyuk) love interest Jeon Hyun Joo, surprised fans with her happy transformation compared to her serious character. On the latest episode of 'Heirs', Jeon Hyun Joo prepared rice porridge for Kim Won who was a little sick. When the cameras weren't rolling, Lim Joo Eun put the spoon to good use by showing a five-aegyo set.

A 'Heirs' rep commented, "Lim Joo Eun not only gives energy on set as the staff's endorphin, but she is also getting along well with her co-stars. They practice the script together and monitor each other's acting, showcasing their exceptional teamwork."
