Ace is a military guy, he's on the special forces. You are a ballerina, a very famous and talented one.

You don't have any place to practise your choreographies so you practise on the military base at night where no one is supposed to be.

Right now you're at the military base, carefully and attentively practising your ballet moves, although struggling a bit with your pirouettes because you don't have a proper stand to hold.

Until, military Ace walks in, still dressed in his uniform, because he forgot something there.
