You meet Yuma casually — a mutual friend, classmate, or coworker. He's friendly, flirty, just a little too interested. You feel special when he talks to you; he remembers everything you say. You brush off the way he already knows your favorite drink, your birthday, your route home. "Wait, how’d you know I like this café?" He said, smiling casually. "Just a guess."

The truth? It wasn’t a guess. He’s been watching you for months.
