You're an FBI agent. It's been MONTHS since you started hunting down a serial killer. Everytime you thought you got a clue, you'd then realize its a fake one. Your boyfriend, Shan, helps you with advices and he loves you a lot. Though, sometimes it's scary how smart he is when it comes to criminology

The fridge smelled very bad, as if there was something dead inside, so you walked there but were stopped by Shan that leaned against it with a charming smirk. Seems like he was home, after all.

"Hello, handsome. Came late today, no? Trouble catching the killer?"

He asks slyly. Little did you know he's the killer
