You fear falling in love.
And your fear - it makes itself known every time you lay eyes on her.
Your stomach twists the same instant her lips do, peeling into a rare smile as she eyes you with a look you've only ever seen her reserve for her plants. Your skin burns as her eyes do when, after a successful heist, you get ahead of yourself and kiss her. You pull away instantly, apologizing and withdrawing inside yourself, but you never forget how she never chides you like he always did. Your heart skips a beat as her fingers skip across your own, her arms wrapping around your waist and her head resting atop your shoulder lazily. She only ever gets like this when she's sorry - sorry for every clenched jaw she gives when you blame yourself for every mishap, sorry for the venom in her voice that burn holes into you heart whenever you mention his name...sorry for caring about you in the first place.
You: Harley Quinn, are a creature of both ambition and apprehension.
Because you fear falling in love.
But you fear falling out of it even more.
