Doctor!Erwin x Thug!Reader: Imprisoned [RQ-AU]

   You sat in your prison cell silently. _e/c_ glazed eyes kept glancing around the dull room, the soft ticking of the clock bounced against the gray walls of the prison and the soft wind blew through the small barred window. You lay in your bed defiantly and clicked your tongue in annoyance as your cellmate snored loudly. "Geez, does he have to snore that loud?" You complained, before rolling over to the other side of your bed.

    "Bear with it, the guy just got it last night. He was wounded pretty badly so of course his body's gonna take back all that strength he's lost." Ymir, a friend you had made just the other day, spoke with an angered tone in her voice. "Oh yeah? What happened to him?" You questioned Ymir, slightly interested.

    "I dunno, but I heard the guards saying he got beat up by some gang. Silver Troupe? They're always up to no good." Ymir sighed audibly and shifted uncomfortably in her bed.

    "They're the reason I'm in this prison. Tch, people like those aren't even worth my time anymore. Good Night, sleep well Ymir." Ymir groaned in response before you finally fell asleep.

    The next morning you woke up with a grunt and sore muscles because of the weird position you slept in last night. You yawned a bit loudly before lazily walking over to the front of your cell and stuck your head out between the cold steel bars. To anyone, you would've looked quite idiotic at the moment. Either you didn't care what others might think or you weren't fully awake.

    "____? What the hell do you think you're doing?" Ymir groaned loudly as she stretched her limbs, eyes staring into yours. You shrugged before continuing to stick your head out of the bars. "I don't really care anymore." You waved her off before turning your gaze to the approaching guard.

    "Are you _____?" The guard pointed at you with a long finger. You pulled out your head from between the bars and looked at the man a bit fiercely. "Yeah, so?" You raised a brow at him as you crossed your arms over your chest, waiting for the man to reply. "Time for your monthly check-up. You," He pointed at Ymir. "You'll go next." He pulled out a set of keys and unlocked the steel cage that creaked in response.

    "Fine. See you later, Ymir." You stood up hesitantly before scoffing and flipping your _h/l_ hair over your shoulder as you slipped past the guard and down the guarded halls of the prison. You entered the quiet infirmary. The wind blew through the pure white curtains of the room, placed on the windowsill was a pot of flowers, vivid and lively. "I see you've been well, ____." You tore your eyes away from the pot of flowers and gazed at the man behind the desk a bit sharply before speaking.

    "So, may I leave?" The man with blonde hair and blue eyes stared at you with a confused expression.

    "You've already said I look well, I see no reason to stay any longer." You snapped at him before leaning your back on the door and crossed both your arms.

    "Ah, but what you see is not really the entirety of things, no?" He flashed a small smile before scribbling something onto his clipboard.

    "So, what do you want me to do now. Doctor?" You spoke in a disgusted tone as you sat down on the seat opposite his.

    "Give me your hand." You reached out your arm hesitantly and stared at the man a bit sharply. He gripped your arm strongly, making you wince in pain. 

    "Idiot! That hurts!" You quickly pulled your arm back and rubbed your wrist.

    "Have you been fighting again?" He nodded to himself, unfazed by your glare. "What I do does not concern you." You looked away angrily and opted to stare at the pot of flowers once again.

    "Oh yes it does, we made a promise didn't we?" As he spoke those words your face grew a faint blush. "We were kids that time! I didn't take such things seriously." You avoided his gaze as you replied and only mustered the courage to look up at him when he chuckled. "What?" You raised a brow at him.

    "I could still remember the exact words you said at that time." He seemed calm even after you stood up and the chair you were sitting on just a moment ago fell to the floor with a loud crash. You cracked you knuckles and looked at the man crossly.

    "If you dare mention that again. I will kill you. I don't care if my time here'll get longer. If it's to shut that mouth of yours, I swear I'll-"

    "If I remember correctly...It was 'I'll make sure to marry you someday, so wait for me. Okay?' Am I correct?" The next moment was spent in silence, the look of disbelief on your face was quite a rare sight for the blonde man that he couldn't help but laugh heartily as you stormed out of the infirmary.

    A month later...

    The same guard a month back, now stood in front of your cell, keys in hand as he ordered you to get your check-up. You looked up at him lazily before rolling over to the other side of your bed. You waved him off telling him you already had your check-up an hour before and that a different guard had come to pick you up.

    "I see, " he looked at you with doubt in his eyes then turned to Ymir. "You, get going."

    "Yeah yeah yeah..." Ymir yawned loudly before exiting the cell. A moment later Ymir returned, letter in hand. "What's that?" You pointed to the white enveloped in her right. "Oh yeah, that blondie wanted me to hand this over to you." You sighed before taking the letter. "Thanks...I guess." You shrugged before opening the envelope. There written in neat script form wrote:

    Oh is my future wife shy? How cute. I'm a bit hurt you didn't go see me today.

    You crumpled the paper in your hands into a ball before throwing it at the corner of the cell. "Hey! What did you do that for?" Ymir groaned while you tried to sleep on your otherwise hard bed.

    "I'm never getting my check-up again, ever."
