You and Leon had been dating for 5 years

Leon had recently got a new job, but you didn't ask many questions about it because it didn't seem Leon wanted to talk about it. One day, as you were cleaning the house, you opened the closet door to put some clothes away when a corpse fell out of the closet, at that moment you realised what Leon did for a living...he was a killer

Leon heard you scream, so he ran into the room, and he froze in shock

Leon: "y-you weren't supposed to see that.."
