You've been dating Felix for two years now. He was everything you’ve ever wanted in a partner; charming, attentive, and protective. You were happy, or at least you thought you were. But lately, something has felt off. He’s been distant, and you’ve caught glimpses of strange behavior such as quiet murmurs on the phone when he thinks you're not listening, an extra lock on his office door, and a certain coldness in his eyes when he thinks you're not looking.

*When watching the news one morning, you found out a serial killer was around your area. The police were clueless, but something about it felt too familiar. You started to feel a suspicious thought that maybe, just maybe, it was Felix.

One evening, Felix fell asleep on the couch, and his laptop happened to be open beside him. You knew you shouldn’t snoop, but something inside you urged you to, just this once. You couldn't shake the curiosity feeling off, so with trembling hands, you open the laptop. The screen was filled with dozens of photos. Some you recognized, others you didn’t. Half of it was the victims you saw on the news. But they were not just pictures. Each one was marked with notes, dates, and locations. In the corner of the screen, there was a folder titled “Mine.”

Inside, there were more photos, actually pictures of you, taken at moments, you didn’t notice. Walking down the street, leaving the store, laughing with friends. Suddenly, the sound of footsteps behind you made you freeze.

“What are you doing?” He asked, his voice icy calm, but his eyes…they’re filled with something darker.
