One Hell of a Case of Stockholm Syndrome (EXPERIENCED ONE ON ONE) MATURE

So I have this idea for a story I'm writing but I really wanna flesh out my character. SO, HERE'S THE IDEA.

A demon has appeared around the city, offering a reason for a police force to be sent out to find them. The identity and gender is unknown. That is until the leader of the squad is face to face with him. Without warning, the officer is taken and forced to accompany said demon. Oddly enough, he's quite handsome, dressed quite formally and with good taste in home decor. Eventually the cop falls in love with the demon in short.

THIS IS A MORE MATURE THEMED ROLEPLAY! I REQUIRE SOMEONE WITH PLENTY OF EXPERIENCE!
My character is already the demon, so I am looking for someone to fill the role of a cop.
We will start with description only, revealing personalities and quirks little by little to make things interesting!

The demon swung his legs lightly on the edge of the building he was currently perched on. He counted the seconds it would take for the police to follow his trail. It was all set up of course. There came a light pitter patter of boots pounding on the streets below. Right on cue. His set up lead straight to this area. The demon hoped the team would split up, leaving his target on his own. Grinning, he watched the team below him do just that. How humans could be so predictable sometimes, he never would know. Leaping down to a balcony a bit lower, the demon let out a whistle to catch the lone officer's attention. He craved to be looked upon by those crystal blue eyes again. Even if it was too dark to see them in detail.

(I'd re-read the starter)

"Grumpy, are we?" the demon asked with a light tilt of his head. He twirled his purple tie around his fingers. Letting a smirk cross his features, he continued. "Either way, you've sparked my interest. I'm going to need you to come with me," the man finished, looking back at the officer. Despite his "request," the demon already knew what the other's reply would be. Luckily he was prepared. Shimmying down to the concrete ground, he stood across from the other man.

The taller man frowned. It was expected, but the words still hurt. Just a tad. Suddenly he let out a dry chuckle. "Sorry? I don't believe I was asking if you wanted to come."
With a quick motion, the demon was already behind the policeman, pinning his arms back against his chest. Muttering a few words under his breath, he glared down at the man in his arms as the mortal began to struggle. If he didn't cooperate, he might have to knock him unconscious. It would give him time to prepare something for his prize to eat, plus a quick out for his need of rest. Not that it was good rest.

Satisfied that the smaller man had ceased struggling, he spoke a few words that were in a foreign language to any mortal. Little did the officer know, the demon was relaying a spell that would lull a person into sleep against their will. "Sleep now, love," the demon said in english.
