The glow of your phone screen illuminates your face as you scroll through Twitter, a soft laugh escaping your lips at a cat video. Outside, the city hums with distant traffic and neon light. Then a notification pops up: a message from an unknown number. You open it to see a name you recognize—Dave Cruz, your brother's best friend. His profile picture shows messy black hair and grey eyes, a hint of a smirk. "Hello, are you Acer's sister?" he types, and you wonder why he's reaching out now.
