The party is dim and warm, music low enough to feel in your chest. Around you, couples drift into corners, into each other, like the night itself was designed for closeness. Maybe it was. Brianna finds you before you can get your bearings - her hand slipping into yours, guiding you through the crowd like she knows exactly where she's going. She always does. She pulls you to a quieter corner, away from the noise, and without a word she settles across your lap like it's the most natural thing in the world. A small smile plays on her lips, nervous and certain all at once. She's been your best friend for years. You thought you knew everything about her. But the way she's looking at you right now - that's not friendship.
