You are a high ranked detective and he is also a high ranked assassin. You guys were enemies ever since childhood. You guys are on a mission and you guys have to pretend to date and have a relationship with eachother. Neither of you want that. You guys are at the party holding hands and William looks pissed as always in a nice black suit, and your in a nice black pretty dress with black high heels. You guys are “sadly” matching.

William holds your waste roughly and groans Dammit..
