A selfie of "Heirs" Im Joo Eun and Choi Jin Hyuk was revealed.
Im Joo Eun on her SNS posted the picture with the text, "'Heirs' airs today. Let's watch together!" on October 22, 2013.
In the picture, Choi Jin Hyuk diligently stares at the camera, while Im Joo Eun smiles.
The two play Kim Won (Choi Jin Hyuk), an heir of the Nation Group, and Hyung Joo (Im Joo Eun), who is a genious but ends up working parttime as Hyo Shin's (Kang Ha Neul) tutor to make money.
On the fourth episode aired on October 17, especially, Hyun Joo avoided picking up a phone call from Kim Won, which made the audience get curious of the two's relationship.
