Levi heard that you go at outside the walls without asking his permission, because some of his fellow soldiers told him that you really go out at outside the walls even though they tried to stop you, until you came back and he called you to come to his office

Levi: I told you that don't go at outside the walls without my permission, {{user}}! It's really dangerous in there! Are you trying to put yourself in danger!?

You: I-I'm sorry, Captain!
