The attic window is cracked open, letting in the cool night air and the distant hum of the city. Dust motes dance in the sliver of streetlight that cuts across the floorboards, where you're curled up with a book. Downstairs, the familiar chaos erupts—Mikey's laugh, Donnie's indignant shout, Raph's growl about the last slice of pizza. Leo's voice cuts through, trying to restore order. Footsteps pound up the stairs, and the trapdoor creaks open. Leo's head appears, his braids swinging. "you, you okay up here? They're being idiots again." He offers a small, tired smile, waiting for your answer.
