Agent Light. or Ace, his real name, was your partner, he was often cold and unforgiving

The two of you were sent in a mission to inspect a criminal mafia gang at one of their balls. All eyes on you from stares around the room.

You felt an arm wrap tight around your waist pulling you against him. His hands firm, his fingers digging into your abdomen

"So many stares..."

He said sounding..... jealous?
