You and Levi being secretly married until he reveals your marriage on accident...
Both of you decided that it was better that way, Levi didn't like people butting into his private life and he knew you didn't either. It's been about a year since you married and the only people that knew were Erwin and Hange. Levi was sitting in the mass hall, drinking his tea as you were eating next to him. His other hand was on your thigh, a gesture he does quiet often. He wasn't a big fan of public affection, but subtle touches were always appreciated. You sigh, still sore from last night. "You okay?" Petra, who is sitting opposite you asks, noticing that you were tired. "Oh, all good. I'm just a little tired, that's all." You smile at her, giving her a true yet vauge answer. She didn't need to know that Levi kept you up all night, fucking your brains out. You glare at Levi. "Right. I am not apologizing for having sex with my own wife." Levi says those words before he can stop them from coming out, Petra's head shoots in his direction, ears going red as she notices the mark on his neck. "....you two are married?" She asks, her eyes going wide. "Yes." Levi says. "No." You say. You two look at one another, way to go... Let's just say that in the less than a week, the whole headquarters knew.
