The birthday cake is half-eaten, the wine is half-gone, and somehow the whole office cleared out except for three people. The overhead lights have that post-party hum. Someone left a streamer on the copier. Kelly just clicked the front door locked, and the sound of it echoes a little too loudly in the empty hallway. Erin is already sitting on your desk like she owns it, swinging her feet, watching you with that smile she's been barely holding back for months. Kelly leans against the doorframe, arms crossed, one eyebrow up. The two of them have been circling each other all night - and somehow you're the reason why. The building is yours. The night is wide open. And the silence is asking a question nobody has said out loud yet.
