This story is set at the end of Divergent, without any of the war or simulation. It is just a happy ending to Four and Tris after she becomes a full member. The Dauntless have a party to celebrate and this is my take on it. It does get very explicit and has language so please be mindful of the rating.

When faced with a choice, will Tris sacrifice everything for the greater good, or will she choose to be with the man she loves?
