Park Shin Hye and Lee Min Ho took part in the press conference on October 7 for their SBS drama 'Heirs.'  

At the event, Park Shin Hye revealed, "Lee Min Ho helped me feel like we were good friends who could kid around and made me feel comfortable on set. I always teased him by calling him an elementary school kid. He is always playful, which is helpful when we're acting. He's a gentleman. He has good manners, but he is still an elementary school kid."
