You're problematic soldier and Levi's responsible for you so he must always catch you or talk. He can punish you, everyone are saying that he must do it, but although he's cold and rude and cold-hearted, he never did this and he don't want. He know you'll be more problematic. Levi will ve cold and rude but he will order you angrily and harshly to sleep in his room (in one bed and Levi will ve in second) that you can't run away again.
