"I feel like I will cry when I think of the last day of filming 'The Heirs' again. I have been feeling so empty after I finished filming for the drama 'The Heirs,' so I have been trying really hard to work out hard and meet a lot of people, trying not to spend time alone," actress Park Shin Hye said.

Park Shin Hye in the interview said that the script writer for drama "The Heirs," Kim Eun Sook, told her to "forget all the acting you've done in the past." Park Shin Hye said, "Before fimling the drama, writer Kim Eun Sook said to forget the acting I have done in the past, because I have done a lot of cheerful roles in the past. On the other hand, Eun Sang is an eighteen year old girl who is always tired for working a lot of part time jobs, and going through a lot of difficult times. Writer Kim Eun Sook wanted me to portray that burdensome feeling."

Park Shin Hye added, "When I was eighteen, that is when I was in the transition of becoming an adult actress. I feel agitated, and I did not like the title of children actress. I thought a lot about how to become an adult actress."
