My Girlfriend, the Barista! (Levi x Reader)

Levi was scrubbing the windows furiously while huffing and puffing at the same time. You stared at him, wondering what in the world was wrong because it seemed as if he wasn’t in a very good mood. Whenever Levi was upset or serious, you would always referred to him as “Lance Corporal Levi” because the manner in which he conducted himself was so unnecessarily strict.
“Freaking windows, why won’t the damn dirt come out?” He muttered to himself as he continued to scrub the windows with great vigor.
“Corporal Levi?” You quietly inquired.
“What?” He drawled. He didn’t particularly like it when you called him corporal, it made him seem as if you were trying to distance yourself by putting a title to his name.
“Are you okay?” You bit your lips and in response, he lowered his rag and sighed.
“No, I’m not okay, my coworkers are giving me a hard time at work and our division might get transferred, which means I might lose my job. I’m expecting that you know how I feel.” He raised an eyebrow at you and you immediately nodded at him.
“Of course, but Levi, I think you should take it slow. It’s not good to overstrain yourself, take it one day at a time and approach each task with a clear head. The more you wreck your head, the sloppier of a job you’ll do. Here, come.” You took his rag from his hands and set it on the table. You led him to the couch and sat him down; he let out a loud sigh. At moments like this, the childish you was gone and replaced with someone more mature.
You got up and headed for the kitchen, making Levi a cup of hot chocolate.
‘Hmm, he really needs something to cheer him; I think I know what that might be!” You quickly got to action, pulling out the cream and chocolate fudge from the fridge and working straight away on the hot chocolate. When you approached Levi, you saw his eyes closed with his head leaned back. You frowned at the emotional condition of your boyfriend, it was terrible when he got this way because it was such a rare sight. Corporal Levi, stressed? If he was stressed, then the world absolutely needs to stop until he catches up.
“Levi-chan?” He gently poked his nose, probing him to give you some attention.
“Hmm?” He opened one eye, peeking at you. When he noticed the mug in your hands, he sat up and graciously accepted the mug from you.
“Enjoy!” You picked up the rag from the table and headed towards the windows to finish cleaning it up.
He stared at the contents in the mug, with surprised eyes, and stared at you with your back turned. His surprised expression slowly melted into a smile, he couldn’t help it. When you did things like this, how could he resist the urge to love you even more?  You were right, he needed to get out of his cloud and realize that he has one amazing person that will stand by him no matter what happens.  
Written on top of the foam on the hot chocolate were the words, ‘Stay Strong Levi! You have Humanity’s Strongest Girlfriend by your side!”
