Cho Yi Hyun and Lomon did 17 takes for their kissing scene in 'All Of Us Are Dead'

Cho Yi Hyun and Lomon made everyone kilig with their undeniable chemistry in the hit Korean zombie series "All Of Us Are Dead."

But did you know that it took them 17 takes to film their kissing scene?

In a video released by Netflix Korea on YouTube, the cast shared some behind-the-scenes stories along with director Lee Jae Gyu and writer Chun Sung Il.

"I'm really sorry to Lomon. I couldn't find where his lips were because I was closing my eyes," Yi Hyun said when they discussed the kissing scene.

"[I said] 'Lomon, I'm really sorry but can we try one more time?' Then he was like, 'Sure,'" she added, and everyone then burst into laughter.

Lomon, who admitted that the kiss was his favorite scene, could not help but smile widely while talking about it.

"Really before shooting that I was like, 'I'm so nervous what do I do?' But after the kiss, I realized, 'So this is why actors do romance movies,'" he said.

"All Of Us Are Dead," based on a popular webtoon by Joo Dong Geun, follows a group of students who find themselves smack in the middle of a zombie outbreak in their high school. With no help incoming, they must find a way to get out.

Since its premiere on January 28, the 12-episode series has landed on Netflix's Top 10 list in 91 countries, including the Philippines.
