All of Us Are Dead actor Yoon Chan-young revealed that his very first kiss happened in the hit Netflix series.

In an interview in JTBC's Knowing Bros, the actor shared that his onscreen kiss with Park Ji-hu was actually his first.

Chan-young plays the role of Lee Cheong-san in the series, the best friend of Nam On-jo (Ji-hu) and to whom he confessed he had feelings for towards the end of the story.

"To be honest, that was the first kiss of my whole life," he shared in Knowing Bros as translated by entertainment website Soompi.

Starting as a child actor in the entertainment industry, Chan-young relayed that he actually predicted that his first kiss might happen on a show.

"I started acting when I was a kid, and over the years, as I kept acting, I started worrying, ‘If I keep this up, I might really end up having my first kiss in one of my acting projects.’ I’d thought that for several years, but that day, [it ended up happening]," he stated.

The actor admitted that he didn't know what to do in the kissing scene that he talked to Ji-hu prior to filming it.

"The night before we filmed that scene, I called Ji Hu on the phone and asked her, ‘What should we do tomorrow?'” he shared.

The actor relayed that since it was his first time filming such a scene, it was their noses that collided during the first takes.
