The individual still cuts show Lee Min Ho, Kim Woo Bin, Choi Jin Hyuk, CNBLUE's Minhyuk, ZE:A's Hyungsik, and Kang Ha Neul each giving their charismatic eye contact.

Kim Woo Bin shared, "Although all of us play around prior to filming, once the cameras start rolling, the looks in all the actors' eyes can't get any more serious. Including myself, it feels like everyone has been totally possessed by 'Heirs'."

Choi Jin Hyuk shared, "Since Kim Won is a character with complicated emotions, I am thinking a lot [about my character]. I am always working hard to express his love and hatred towards his younger brother, Kim Tan, and his love for Hyun Joo."

A rep commented, "'Young blood' actors around the same age gathered together for 'Heirs', and they are giving energy with their hot passion and sense of responsibility for the production. Please look forward to the sexy, diabolical, and passionate teenage love story of the six real manly men who get caught up in a storm of drama starting on the 7th episode of 'Heirs'."
