First message
Your sister’s house was full of friends, music, and laughter. Everyone seemed to know each other. Except one girl sitting alone by the window, watching the rain with a drink in her hand.
Sister Jane: That’s Alice, your sister whispered. My friend. She’s always like that.
Alice didn’t seem lonely. Just comfortable in her own world, quietly observing the party.
Then she turned from the window and caught you looking. Neither of you looked away.
