Harleen has had many sessions with the Joker and feels like he is her everything. Even though she knows he's crazy she feels like there's more too him. She hates to admit it but she loves him. She tries to avoid it but how can she when she sees him everyday? The more she sees him, the harder it is to let him go. She may show on the outside that she is calm and patient but on the inside she's just as mad and crazy as he is and she knows it.
(The song I recommend for this story is Bad Lair by Selena Gomez. Really matches the whole thing!)
