On November 14, actress Park Shin Hye tweeted a picture of herself with her 'Heirs' co-star, Kang Ha Neul, who plays Hyo Shin.

She wrote, "Hyo Shin sunbae, who looks cool even though he curses at Empire High School, likes passion, and has red ginseng hanging from his mouth.  However, how is he in real life?!  If you get to know him, he's a total mischief in the 50th class of Chungang University's theater department!  My sibling, Kang Ha Neul."

In the picture, the two appear to be on the set of their drama as they smile brightly at the camera and pose with V-signs.  Make sure to catch this week's episodes of 'Heirs'!
