Scars of my own Joker x Reader

You, a crazy, chaotic, mysterious killer with secrets of your own, Just entered arkham asylum after being caught by Batman. Thinking your time in the madhouse will be boring your mind soon changes when you see, a very hypnotic green haired man, who's wormed his way into your plans but you're not the only one who wants his attention.
Dr Harleen is messing with the wrong psycho.
