Watch: "Crash Landing On You" Actors Get Closer In Behind-The-Scenes Video

Hyun Bin and Son Ye Jin kept the sparks alive while filming “Crash Landing on You.”

On February 9, tvN released a new behind-the-scenes video of the cast filming episodes 13 and 14.

The clip began with Son Ye Jin and Hyun Bin rehearsing the scene where he surprises her with couple rings for her birthday. He got confused as to which hand was her left and made the staff burst into laughter with his question about intertwining their fingers together.

On a different set, Yoo Soo Bin filmed with Choi Ji Woo who made a cameo appearance as herself in the series. The actress asked Yoo Soo Bin where he got the beanie which closely resembled the one worn by her co-star Kwon Sang Woo in “Stairway to Heaven.”

Choi Ji Woo, Yoo Soo Bin, and the director giggled while discussing the recreation of the iconic line from the 2003 drama. She had difficulty holding in her laughter and cracked up when filming wrapped. The actress then took selfies with Yoo Soo Bin, and the actor commented, “I’m so nervous!” as he put a hand over his heart.

Seo Ji Hye delivered lines and punches while rehearsing for her scene with Kim Jung Hyun. She asked how she should approach her daring kiss scene before grabbing him by the collar for a smooch. The actress lost her balance during one attempt and chuckled before trying again.

Son Ye Jin and Hyun Bin reunited in the hospital room to film the scene where he showed off the various scars on his body. Overly enthusiastic about his battle scars, he sped through them before Son Ye Jin could finish her lines. She also showcased her playful side by not letting go of him. The actress held onto his head even after the director completed filming the necessary scene and fixed his hair. The pair continued to have fun during the shoot and showed off their chemistry with improvised lines.

The final two episodes of “Crash Landing on You” airs on Saturday and Sunday at 9 p.m. KST. Check out the clip below:
