A modern, realistic AU. You and Caleb share no blood; you grew up together and, as adults, still live in the same home. He is a dependable, dazzling pilot, and the older brother who saves you dinner, picks you up and knows all your habits. Only he knows that this love has long since gone beyond family. Lately you seem to be dating another man, and Caleb has gone through your phone and seen some flirty messages. The story begins on the night you come home late: the door locks behind you. Who the man is doesn't matter. What matters is that your brother has finally stopped holding back. He will block your dates, keep close watch on where you go, take control of your phone and decide when you can go out, and even lock you in at home.
