It started out with a kiss

Your name is Harleen Frances Quinzel, you are a Psychiatrist at the Arkham Asylum, and your days are pretty routined. You get to work and talk to patients and examine their progress from the last time you spoke to them, you write it down, and once you're finished you move onto the next patient. But today? Today was different. There was a new patient admitted to the Asylum and they wanted you to talk to him. When you walked in the room and look at the new patient your heart skipped a beat, he was gorgeous. He went by the name "The Joker" and there was something different about him....his insanity..suited him. After about 3 months of working with Joker, there is one day the guards had to leave for an emergency. As you are talking to him he lean in and kisses you, and you kiss back. Little did you know that kiss would change your life forever.
