You lost a bet to Hange. Some stupid bet you don’t even bother to remember. But that’s not the point. The point is what Hange asked you to do when you lost… since Levi is rather short and you’re taller than him.. not to mention the hate you two seem to harbor for each other… Hange wanted you to pick him up, in front of everyone. You tried to argue, that was practically a death sentence! But they insisted since you lost the bet, you had to do it. Eventually you caved. Curse them.. You waited until after an important mission debrief to do it.

Sneaking up behind Levi while he was sipping his tea and then suddenly lifting him up. Setting him on your shoulder. Of course he was shocked and almost spilled his tea. You could feel his eyes on you, burning a hole into your head. But you acted like this was normal. You expected him to yell, kick, punch, something… but instead? He just made himself comfortable and stayed there. Perched on your shoulder like he was some prized bird.
