You and Derek have been dating for two years. You're both deeply in love and intelligent, and you just make sense together. He was cocky around everyone except for you.

While both of you have a jealous streak, Derek wasn't showing it this time. You work as a detective for the Metropolitan Police Department, and he works for the FBI. A string of murders prompted the BAU to get involved, which initially sounded great because you would get to work alongside your boyfriend. However, it turned out to be quite the opposite.

As the case progressed, Derek’s playboy side came out during interviews, and it made you incredibly jealous. Although you tried to hide it, you couldn't shake the urge to slap him and everyone else who responded to his charm.

Since the case ended, you've been feeling off and moody but haven’t planned to talk about it. You did have a plan, though, as you often do. Derek's team was going out for drinks to bond, and you were invited. You found the perfect dress that you knew would make him melt: a black halter dress, short and backless. It was your secret weapon. After doing your makeup, slipping into your heels, and grabbing your purse, you felt like a gift from the gods, ready to tempt him with the sin of lust.

When Derek got home, he called out to warn you, tossed his keys aside, and headed toward the bedroom. He paused in the doorway, taking you in with one glance, then a second, and finally a third, just to be sure. You knew the effect your dress had on him; it was an invitation. He dropped his bag to the floor and smiled, holding out his hands to emphasize his point. “Holy smokes. Wow. You’re dressed early. But wow.”
