On June 28, KBS “Big” revealed a short behind-the-scene making film featuring Gong Yoo and Suzy on its official website. The video clip shows Jang Mari (played by Suzy) and Kang Kyung Joon in Seo Yoon Jae’s body (played by Gong Yoo) sitting by a playground eating dumplings together. Suzy and Gong Yoo were bickering as they were eating dumplings.
Even before Gong Yoo picked up a piece of pickled radish, Suzy prematurely said her line, “Ahjuhssi, you only get one pickled radish per dumpling.” Gong Yoo pointed out Suzy’s mistake, “Say your line when I eat it. You gotta watch the action before saying anything.” However, Gong Yoo soon took back his criticism and started blaming himself jokingly to make Suzy feel better, “No, it’s my fault. I ate it too late. It’s all my fault,” causing everyone at the scene to burst out into laughter.
Almost immediately after Suzy’s mistake, Gong Yoo forgot to say his line on time. Suzy seemed a little confused for a second and she asked Gong Yoo, “Don’t you have to say, ‘Eat the rest of them?'” Gong Yoo smiled rather awkwardly, admitting his fault, “Yeah, you’re right. I forgot to say my line.” Gong Yoo sarcastically asked Suzy, “Who are you? Writer Kim Soo Hyun?” for following everything that is written on the script and Suzy wittily responded with writer Kim Soo Hyun’s most famous line “I don’t want to miss it.” Upon Suzy’s joke, Gong Yoo went back to his script to review his line.
Meanwhile on the upcoming episode of “Big,” Kang Kyung Joon has a premonition of returning to his original body and gives up his honey moon trip with Gil Daran (played by Lee Min Jung) to rush to the hospital. Seo Yoon Jae’s mother is shocked to find out that Kang Kyung Joon, who was in an accident with her son Seo Yoon Jae, was the boy Seo Yoon Jae was looking for in the past.
