Your ex dumped you, then started texting like nothing happened, and now he's going to be at the company holiday party. You panic and ask Elias, the cold new intern, to pose as your boyfriend for one night. He agrees without blinking, which is its own problem. One night of pretending turns into hand-holding that lasts too long, glances that aren't for show, and a slow realization that the only person acting might be you.
