Ahn Hyo Seop, Kim Sejeong, More Display Closeness Through Improvisation Set of 'A Business Proposal'

Based on the popular web novel of the same name, "A Business Proposal" follows the chaotic romance of Shin Ha Ri (Kim Sejeong) who goes on a blind date with her company's CEO Kang Tae Mu (Ahn Hyo Seop) in place of a friend. They did not know each other's real identities.

The newly released behind-the-scenes videos contain unseen footage of episode 9 and 10 during its filming.

It starts with the hilarious double date between Kang Tae Mu, Shin Ha Ri, Jin Young Seo (Seol In Ah), and Cha Sung Hoon (Kim Min Gyu). They showed off their closeness by laughing over something as simple as opening a safe.

The quartet then gather for their meal scene. Kim Sejeong jests about their precious moment being rare, and the cameramen should capture it a lot.

As the filming continues, Shin Ha Ri spills soda on Kang Tae Mu and ruins his shirt, Ahn Hyo Seop makes everyone laugh on set as he suddenly improvises and says, "I can just switch clothes with Sung Hoon."

Next, when Shin Ha Ri lends the former a shirt, Ahn Hyo Seop insists on changing in front of her and comments on his exaggerated gestures.

On the other hand, Kim Sejeong films Ahn Hyo Seop and asks whether he is confident about going shirtless on camera.

Ahn Hyo Seop answers, "Everyone's standards are different. Shin Ha Ri must be regretful."

When Kim Sejeong agrees, Ahn Hyo Seop replies, "It's okay. In the finale..." then he was censored for spoilers.

In the next scene, Kim Sejeong and Ahn Hyo Seop sneak out and get caught by her brother VICTON Byungchan,. He plays the role of Shin Ha Min.

Kim Sejeong tries to hold in her laughter but the director laughs instead. The siblings explain that it was Ahn Hyo Seop's improvisations that made them laugh.

The director responds, "Live out your dreams!"
