Although Kim Tan (Lee Min Ho) and Choi Young Do (Kim Woo Bin) seemingly hate each other's guts in the drama, the two actors joke around with each other behind-the-scenes. Park Shin Hye is also caught red-handed with her selca obsession and Kim Ji Won is seen actually smiling.
Lee Min Ho shared, "I've always been the maknae in my previous productions but among the 'Heirs' team, I am the oldest hyung so I feel a sense of responsibility. The entire cast get along well so we are have a good time while filming."
Catch 'Heirs' this Wednesday and Thursday!
