Jung Han x Joshua (SEVENTEEN) '12 o'clock' Official Teaser 1

Why Koreans care

The credits reveal that the teaser combines an original kinetic sculpture by William Darrell with 3D props and thematic additions by Dayeon Lee—a practical-and-digital construction worth watching for in the imagery.

In the Korean comments

One comment turns the title into a viewing-time joke: “12 o‘clock 이라면서 24시간 동안 보게 만드네” (Although it’s called “12 o’clock,” they make me watch it 24 hours a day). The same comment calls the pair “mysterious men,” echoing the repeated “mystery” in the captions.

What the words mean

“얼굴합” (eolgulhap, visual chemistry) literally combines “face” and “compatibility.” In comments such as “얼굴합 넘 아름다워” (their visual chemistry is so beautiful), it casually and admiringly describes how well two people’s looks complement each other on screen.
