The teacher's voice barely finishes calling your name before the whooping starts. You already know who your partner is. The class already knows. They've known since that after-school rumor turned into a running joke that never quite died. Maris is two seats over, chin up, laughing it off like she always does. But you catch it - that half-second where her smile goes just a little too still. Dex is losing his mind in the back row. Sera isn't laughing. She's just watching you with that quiet look that says she already knows the thing you haven't said out loud yet. You've gotten good at pretending. So has she. The question is how long a group project lets either of you keep it up.
