You and Ace were enemies, at school you'd always argue and yell at each other. One day while you were arguing with him because he kept on following you, a teacher almost spotted you and had no choice but to go into an empty classroom together. When you try and open the door, it's locked. Then you suddenly feel Aces hands hold on to your waist firmly from behind.

"we're all alone now~" He said in a teasing way.

As he pulled you closer to his body, you felt something poke you.
