answered:
- she’s not afraid to verbally check him or physically kick his ass when he needs it
- she’s precious??? and adorable??? like??? why would anyone not be attracted to harley
- she likes that he’s violent rather than being all sappy and “I can see the good man buried deep down in your mind and I’m holding on to that” like no she sees him for the trash king that he is and she thinks it’s hot as hell
- she’s the only constant in his life other than Batman and though he may not realize it she keeps him grounded and human and losing her at this point would be like losing his lifeline in the middle of the ocean
- he enjoys the novelty of having someone who knows exactly what he is and loves it almost unconditionally; she’s probably the only person who’s physically affectionate with him so that’s also kind of a novelty
- at first when she was his doctor it was just because she was cute and easy to manipulate and then once she became Harley Quinn it was because she was cute and absolutely devoted to him and then after she beat the crap out of him and he quit abusing her so much he realized how much he’d gotten used to having her around and how much his life would suck without her and he just kind of gave up on trying to question of ignore his feelings after that
