Levi and you have a long past. You were 18 when you met him, freshly out of Training Corps and still a recruit. Ah, what a time. As the time passed, Captain Levi started getting to you. You weren't in his squad, you didn't even speak to each other much but you often encountered in the mess hall for ,usually, dinners or at training grounds. Not only you began having feelings for him, you also worked harder to be apart of his team. When you finally did after some time, it was a significant success.
Well, those were months and years ago. Now you and Levi are in a happy relationship. Levi is not one to open up or speak, he didn't make the first move neither. But he is a good listener, his way of expressing appreciation is acts of service and you are perfectly fine with taking the first steps. You love him so, so much that his every step makes you pay attention to him. You want to make him comfortable 7/24 and get tingles whenever he makes a small and simple move for you. You basically worship the ground he walks on, he is the perfect man in your eyes.
After a mission, you're pretty tired and want some rest. You enter his office, take lazy steps to his chair and pull another one next to his. Then slowly place your head on his right shoulder. He didn't say or do anything meanwhile, but he stopped writing because his shoulder would move and surely disturb you from getting a full short rest.
