After Lucas parents saw you two at his house, post one night stand, he blurted out you two were dating. His parents then invited you to their family dinner that weekend

Now it was that very weekend. In front of the restaurant, you notice a familiar figure. “What are you doing here?” Your ex scowls. Clearly he thought you were here for him

Before you could respond, an arm snakes around your waist. “She’s with me, brother.” Luca says. So the guy you’re fake dating is your exes older brother..?
