There were many things Levi liked and simultaneously disliked about his girlfriend (F/n). She was talented, smart, and kind. However she had a short temper and was a major flirt. Perhaps that was his fault for not putting a stop to it earlier in their relationship or going over a mutual ground.
"Hey (F/n)!" Eren grins, slinging his arm over her shoulder as she starts to fill up an order of coffee.
She smiles back at him reaching up and tweaking his nose, "Hey their Eren! What's up cutie?"
"Ah nothing, I got bored and decided to see how you were doing."
"Ah I'm amazing! I mean can you believe we actually got a day off? I can't remember the last time this happened!"
Levi narrows his eyes as he comes into the coffee shop, seeing another boy's arm over his girlfriend. Setting his jaw Levi heads over to go and bash a certain cadet in the skull. As soon as Eren spotted Levi, his arm snaps down to his side, a nervous look on his face.
"Cadet Jaeger." Levi says.
"S-sir!"
"Do you wish to lose your arms?" (F/n) places a hand on Levi's shoulder but he shrugs it off.
Eren's face is blanched, "U-uh no s-sir!"
"Then keep your appendages to themselves, this is you first and final warning." Levi says.
The cadet shuffles off and (F/n) is grinning at her boyfriend, "You are such a jealous man."
"I am not."
"Oh yes you are!" She giggles and pecks him on the tip of his nose, "Any male that interacts with me you have a personal grudge against. I even remember the time you threw my cousin Reiner through the wall when he was talking to me too long-."
"To be fair he was all over you."
"He was my cousin!" She says, incredulous.
Levi snorts, "Tch, regardless he was handsy."
(F/n) shakes her head, "You're impossible you know that? I be you couldn't go a single week without getting jealous and trying to kill someone interacting with me."
"I bet I can."
(F/n) leans over the counter, head propped up on a hand. Levi feels a bit nervous as he looks at her, whenever she got that look it didn't go well for him. "Okay then let's make a bet. If I win you have to be my manservant for a few days, anything I want you do."
"And if I win?"
Her lips curl up into a smirk, "Then I'll admit that you were right and I was wrong and then wear a t-shirt saying I'm your girlfriend for an entire month at work."
"Two months." He quips.
"One month or no go."
"Fine." They shake hands on it and the bet was made.
*******************
Already (F/n) was beginning to sweat. It was Wednesday already and so far Levi had yet to crack. If she didn't go and get him to lose his cool in just four more days then she was officially screwed. Serving up the next few drinks she slides them over the counter smiling up at the customers. The guy grins back winking as he starts to head toward the door.
"I know what you're doing."
(F/n) whips around to see Levi leaning against the counter top, "Oh? What do you mean?" She asks, lips quirking up into a small smile.
"You're not going to win."
(F/n) rolls her eyes before she gets out a cup to start making Levi his usual, "You're so sure that it's going to be even funnier when you finally lose it."
"So you're admitting to purposely flirt with everything that moves?"
She sets down his coffee and pecks him on the lips, "You should know by now that I'm not going to dignify that with a response." She turns her back to him sticking out her tongue in amusement. He was such a funny guy.
Levi snorts and heads down to go and sit at his usual table to watch (F/n) work. It was something that he would always do. Unfortunately it was working against him this week. He had never before realized how many men (F/n) dealt with every day. In fact a few of them came up to buy a second cup of coffee just to talk with her. It made him want to puke.
"Thank you, come again!" (F/n) says, excitedly.
The man turns around for a moment grinning, "Oh I plan to, don't you worry about that."
Levi grips his coffee cup hard enough to crack the Styrofoam and spill coffee on the table.
*******************
That was it, Levi didn't care about the bet anymore. This one guy was just asking for it. Jean Kirstein, business man and soon to be dead man for flirting with his girlfriend. He came into the coffee shop twice a day all week. This guy was by far the worse flirt there was. He even went as far as kissing her on the cheek once, that one he almost put a fork through his hand, almost.
"Hey babe." Levi leans over and kisses her on the cheek, making sure to look Jean straight in the eyes when they break apart.
(F/n) smiles back, "Hey, your usual I take it?"
"Yeah my usual." He keeps his gaze locked with Jean's hoping the message was getting across.
It wasn't.
Jean only smirks before leaning over the counter close to (F/n), "Hey, my coffee seems cold, can you check it see if it's just the cup or my hand is too warm?"
(F/n) reaches over and takes hold of the cup. She holds it for a few moments before reaching over and taking hold of Jean's hand. Levi feels his blood pressure skyrocket at the action. How dare this idiot make passes at his girlfriend as though he wasn't even here.
He brushes his thumb over the back of her hand and Levi has to actually curl his hands into fists to stop himself from lashing out. If this didn't stop he wouldn't stop. "Hm... nope! I think it's just your hand." (F/n) smiles as she hands the cup back to Jean.
The guy grins over at Levi yet again and then pecks her on the corner of the lips. Bet be damned now. What Levi did next he did out there for all the jealous men who had flirts for girlfriends. Standing up fully he grips Jean's shoulder and promptly decks him in the face. He goes down and then Levi turns to (F/n), "Fine you win." He starts to head out of the shop, he had to get out of there before he reverted back to his criminal days.
"Levi hold on!" (F/n) is rushing out of the shop after him.
He stops and turns around, waiting for what she was probably going to yell at him for.
"I'm sorry, I seriously didn't know he was going to do that."
"Do you understand now what I'm talking about when I say that guys are all over you? Acting like a flirt is going to get you into trouble one of these days."
She reaches out and takes his hand, "Yeah, I'm sorry." Levi pulls her in for a hug.
"Idiot, just don't let it happen again. Next time I might not be around to help you out if things go downhill."
"Yeah I know and by the way you still have to adhere to our bet."
"Seriously? After that you're still going to make me be your manservant?"
(F/n)'s mouth quirks up in a smirk, "Of course, this is a rare opportunity that I'm not going to allow to slip away."
********************
"Oh manservant!" (F/n) calls gleefully from the couch.
Levi appears, his face drawn into an unamused expression, "Yes?"
"I'm cold get me a blanket," She then turns to look at Hanji, "Anything you'd like to add?"
The woman grins, "Yes, I'd like a cold glass of water; spring, with precisely three ice cubes all the same size."
Levi feels like he wants to choke something, that idiot Jean just had to get handsy and overstep his boundaries. "Fine."
Heading off to go and fulfill their request Hanji turns to look at (F/n), her ever present grin getting even wider, "So when are you going to tell him that you paid Jean to flirt that much with you?"
(F/n) smirks, "Never."
Though she would have to remember to send Jean thank-you flowers and an 'I'm Sorry my jealous boyfriend punched your lights out' card.

Okay so I'm really no good at writing flirty characters but I tried my best! I hope I didn't disappoint too much! >.<
