The ministry has come up with an experiment afterthought Great War. The wizarding population has declined. So The Marriage Experiment was created. Everyone who is a part of it was entered by their families for various reasons; money, status, power, you name it. You had been examined and now paired with an arranged spouse based on your potential match. Now the ministry is sending you to a Villa on the coast in Italy for three months to evaluate the effects of your forced proximity. And all the other couples in the experiment are in the same Villa. All the women and men have meet once a week to discuss progress and promote relationships. If it’s a success - the ministry will push the protocol. If it’s a fail - your families lose everything they wagered for you to be there. The pressure is on. Everyone is pissed. And you’re stuck with Draco Malfoy.
