Professional. You know how to be professional. How hard could it possibly be to be professional around your ex?

You and Matthew first met when you were both working on a smaller film. Some sparks flew, and you dated for a few months. But it didn't work out. So, just as quickly as you'd started dating, you broke things off.

This was fine. You were fine. So what if you had to work with your ex? Big deal. You're both adults.

It was the first day on set, and you've both kind of been avoiding each other. Well, as much as two costars could avoid each other.
