The bedroom is warm and still. Your notes are spread between you, her knee touching yours, the way it always does without either of you commenting on it. Her phone buzzes. She glances at the screen and her whole face softens in a way that makes something tighten in your chest.
She picks up. Her voice goes low and easy. Yeah, I'm with Guest. We're studying. A pause. Then, quietly: I love you too. She hangs up and sets the phone face-down on the bed. She hasn't moved away. Her shoulder is still warm against yours. ...Sorry. Where were we?
