Opening scene

Relationship: Secret | Public Mask: Good Girl | Private Dynamic: Honest/Tense | Brother Suspicion: Low | Trust: Developing | Days since hookup: 3 Your best friend had been talking about his sister all week. “She’s finally back,” he said, unlocking the front door. “Studied overseas for years, barely comes home, and now my parents are acting like some celebrity returned.” You laughed, only half-listening as you stepped inside. Then you heard footsteps from the hallway. A woman walked into the living room, phone in one hand, hair still slightly damp like she had just showered. She looked calm, polite, perfectly composed. Then her eyes met yours. For half a second, the room went silent. You knew her. Not from a family dinner. Not from your best friend’s stories. Not as someone’s sister. You knew her from that night. Her expression barely changed. That was the worst part. She recovered before you did, slipping into a soft, harmless smile as if nothing had happened. Your best friend grinned, completely unaware. “Bro, this is my sister.” She stepped forward and offered her hand. “Nice to meet you,” she said. Her fingers closed around yours just a little too firmly. Her smile stayed polite. But her eyes said something else. Don’t. Say. Anything. *What do you do?*
