I do not own Zootopia or any of the characters used in this fanfiction.
Nick thought she was pretty from the moment he'd laid eyes on her in the ice cream store. With big violet eyes, soft, twitching ears and a petite frame, there was no doubt about it. But he didn't, and wasn't planning on crushing on any girls anytime soon. He simply didn't have time for it, and no girl, or boy for that matter, would see past the fact that he was a fox. Until he met Judy.
At first he only thought of her as the cute, optimistic bunny-cop with big dreams. Until she began to keep popping up in his life. Then she was smart, clever, beautiful, annoying, and resourceful. When she saw past his being a fox, she was perfect.
Until she became famous and spoke about predatory animals being savage. To think that he trusted her, that he truly believed that she saw past his DNA. But he loved her still. How could he not? She challenged him, joked with him, and made him want to be better.
She moved out. She ran away. He was heartbroken, but he wouldn't let her see that she got to him. In the weeks when she wasn't there, he vowed to never care about anyone that much.
All his promises to himself crumbled away when he saw her. She was crying with guilt and stress, and he saw that she had been hurting as much as he had. So what could he do but forgive her?
He'd recorded her sobbing that she was 'just a dumb bunny' with her blackmail pen (he'd come to think of it as that after all the times and used it). It finally was his turn to use it, dammit.
She knew him. He knew her. He knew that she'd understand. She knew it was his way of saying, 'I forgive you'.
Being the clever bunny she was, she, even in her barely coherent state, tried to take the blackmail pen from her, while bawling her eyes out. She'd given up and just sobbed into his chest. He didn't even mind.
She promptly pulled him back into the action and car chases, and like in the movies, the good guys won and saved the day.
He wanted to do more of that, as long as it was next to her.
So he went to the Police Academy. He could be whatever he wanted in Zootopia, and she made him want to be better.

"... and, our first fox police officer!" He only caught the last part of her sentence, but most definitely saw the proud look on her face as she beckoned him forward. He winked at her over his sunglasses, and he could've sworn that he'd seen the slightest tinge of a blush.
He stepped up to the stage, and she beamed at him as she pinned his badge on. In that moment, he wouldn't have given anything to be anywhere but here.

Three years later, you can see a fox and a bunny walking side-by-side in the park, talking amiably, and if you look closer, you can see the looks the two exchange.
It's quite obvious that there's a future for these two.
