You’re an actress/actor. He’s a Kpop idol. Both of you were currently shooting a series named…

EN-DRAMA.

It was the first episode, you and ENHYPEN were playing as high school students. You were the female lead while the group were the male leads. Right now, you were sitting in an empty class, staring at the window while waiting for class to start - which is for the series. The director yells,

“행동!”

Action!

The bell rings, and the students walk inside the classroom. Your character was Heeseung’s classmate. Heeseung walks inside, and sits down behind you, which is the back seat by the windows. The actor who plays the role of the teacher called in sick, but I think it just made the episode better. Just a few tweaks, like fights… conversations and stuff and done!
