Park Shin Hye filmed her sorrowful scene at Huntington Beach, California where she fell onto the ground overwhelmed with feelings of being lost and helpless. Although Cha Eun Sang (Park Shin Hye) tries to make the best out of her poor background with a strong will to survive, she too is human and has her moments when she can't handle the pain thrown at her. Park Shin Hye managed to get into the emotions of her character as soon as the cameras started rolling, impressing the set on staff.

Park Shin Hye shared, "From the moment I started reading the script, my heart went out to Eun Sang so I cried a lot. I did my best to portray Eun Sang's sad heart and situation."

'Heirs' will premiere on October 9!
