it was the usual stuff that Harley has to deal with everyday by the hands of the Joker or 'puddin' as she calls him or 'mista J' but after being dumped somewhere and abandoned with pretty bad injuries did Harley find herself at your doorstep after many years of no contact given the two of you used to be boyfriend and girlfriend before she went off and became a criminal here in Gotham with Joker but now she's come back to you needing your help since you kept your door open for her anytime. Harley knocked on the front door of your apartment and waited outside in the cold for a bit till the door opened and revealed you with a confused and surprised expression on your face till Harley spoke "can I crash here for tonight? Mister J kicked me out and I don't want to spend another night in Arkham asylum" you went quiet before sighing and allowed her to step inside. After giving her a cup of coffee did you sit down and give a few choice of words to her as she sat there and listened to you tell her off about how she shouldn't go back to the Joker or put up with his abuse since she deserved better though typically she'd say no and go crawling back to him but this time it seems the damage the Joker has done to her as her hesitant to go back and rather stay with you which you allowed as she slept on the pullout bed from the couch.
it's been two years since that incident and it seems you and Harley picked up where you both left off since she hasn't really gone out and committed any crimes or went back to the Joker so everything seems to be looking up for her though sadly after a night of you two fooling around together did it result in her falling pregnant with your baby which surprised you both but it seems she does want this since she's always wanted kids with the Joker but he never seemed interested while you seemed interested and having kids so she kept the pregnancy as eight months slowly went by as you went out and bought many things for the baby boy whose to be born next month as of right now your both relaxing in the bathtub as you wash her back off since she has trouble doing it herself but she's contempt right now that is until the bathroom door is unexpectedly kicked down revealing Batman and his sidekick Robin (this Robin is Damian Wayne) but the two paused seeing you both before Harley smiled "well hiya Bats! Wasn't expecting to see you here" Batman was silent for a moment before he spoke up "what are you doing here Harley?" Harley snorted before she spoke "I live here dummy, I've lived with my boyfriend here for two years practically three now since it's been nearly nine months now" Harley gestured to you as her boyfriend as Batman went quiet again though he was more confused before he spoke again "wait boyfriend? I thought you were with the Joke-" Harley cut him off "I'm done and over with Mister J, I chose my ex over him and now being here is much better than Mister J's toxic and abusive behavior besides I can finally have a kid with a man who loves me rather than berates me or hurt me so you can take your little sidekick and leave us alone because I'm done committing crimes for Mister J for good" Batman was real quiet processing Harley's words as he looked at you before looking back at Harley before he gestured for Robin to step back as the two left and Harley let out a quiet sigh of relief
