The sun had set an hour ago, casting the parking garage in an eerie darkness that was only broken by faint yellow lights from overhead. Jack was the only one left on his level and after the day he had, he was ready to go home and have a few drinks. He had been trying to think of ways to get you to forgive him all afternoon. You weren't returning his texts and every time he called, he couldn't get through. He didn't want to stop by your dad's gym. Tony and the fighter he was training, Bucky, he thought his name was, always looked at him as if they wanted to beat the shit out of him. Going by your apartment would be the easiest way to get to you. Jack was confident that he could talk his way out of the hole he was in.
A little groveling, a sweet smile, and the promise to never do it again would have you forgiving him in no time. Of course, he wouldn't mean a fucking word he was telling you. He wasn't a one woman type of guy, but he did enjoy having someone at his beckon call. Someone to be his date to company events, to hang out with when he was bored, but most importantly to fuck whenever he wanted.
Jack walked down the empty rows of the parking garage to his car, dialing a number on his phone. Stacey was a great fuck, but she wasn't suitable for public display. You were charming and smart. His co-workers loved you and he could usually get you to agree with anything he wanted to do. Stacey's voice squeaked through the phone as she answered.
"Stacey, baby. I'm going to be a little late coming over tonight. I have something that came up and I have to take care of it right away."
Jack unlocked his car and climbed in, setting his briefcase in the passenger's seat.
"You know you're my number one girl, Stace. But I have to apologize to Y/n. I told you, our relationship is strictly for professional appearances. I have to maintain that for now, baby. Don't get jealous on me now. As soon as I can I'm going to completely end it with her and you'll take her place. I'll see you in a few hours, baby."
Jack cut the call and scoffed at how easily she believed the lie. He was never going to end things with you. In fact, if you agreed, he planned to eventually marry you. Your presence in his life made him look like a responsible, reliable guy. That was the image he needed to maintain if he wanted to become the CEO of his brokerage firm sooner rather than later.
Jack reached for his seat belt as he thought about what he was going to say to you. His hand was grabbed and pinned behind the headrest as a knife came to rest at his throat. Jack stopped fighting as soon as the cold blade was pressed against his skin. Looking into the rearview mirror, he met a pair of steely blue eyes. Dark brown hair hung around the sides of the man's face. A hood was pulled over his head and a black bandana was tied around the bottom of his face. The leather of the gloves he wore creaked as his hand tightened on the blade.
"W-what do you want? I-I'll give you whatever you want, just please don't hurt me!" Jack wailed as tears began running down his face.
"Pathetic." The man chuckled deeply. "I don't want anything of yours. What I want is for you to leave Y/n alone."
Jack's face slowly transformed into a smug smirk and his tears dried up. This wasn't a robbery, it was a scare tactic.
"So you do want something of mine. You want Y/n."
"She is not yours." The man growled and pressed the knife hard against Jack's throat, drawing a thin line of blood and making Jack hiss in pain. "She is mine now, so back the fuck off or I'll find you and finish this. I know how to make people disappear and I won't have any regrets."
"I can stay away, but she'll come crawling back to me." Jack chuckled. "When she comes begging me to take her back, I'll be there with open arms."
The man's eyes grew harder and he pulled back on Jack's wrist, the bones made a sickening snap and Jack screamed in pain.
The man released Jack's broken wrist and reached to pull the bandana off his face. Jack's eyes grew wide as recognition set it.
"Bucky?" Jack seethed. "I should've fucking known it was you. You always looked at her like she was a piece of meat and you were a lion on the prowl. You really think she's going to choose an unknown, wannabe boxer over me. It's not going to fucking happen!"
"We'll see about that, Jack." Bucky gritted through clenched teeth. "Are you going to leave her alone or not?"
"You'd have better luck winning your little boxing match that's coming up."
"Have it your way." Bucky smirked at Jack through the mirror and swiftly slammed his head forward into the steering wheel.
Bucky's fist connected with Jack's face when his head fell back against the headrest. He wrapped his hand around Jack's throat and squeezed until his entire face was turning red.
"Do you know how easy it would be for me to snap your fucking neck?" Bucky whispered harshly. "Leave. Y/n. Alone. This is your one and only warning."
Bucky released him and climbed out of the car. Jack leaned against the steering wheel holding his throat and gasping for air. His door suddenly swung open and he scrambled backwards hitting the center console.
"Report this at your own risk. I know people in this city. The charges will never touch me and you'll end up with a target on your back. Got it?" Bucky's voice was menacing and set Jack's body trembling.
"Y-yeah. I promise I won't say a word."
Jack watched Bucky disappear into the shadowy outskirts of the parking garage and heard his footsteps growing fainter. Jack slammed his door shut and peeled out of the parking garage, intending to keep his word and avoid you and Bucky at all cost.
